Do you have any questions?

We'll be happy to answer them.

In this section you will find answers to the most important questions about the CMS4VR system.

Read carefully.

According to our knowledge, the conditions necessary for the operation of the CMS4VR system are met by over 97% of servers.

Even regular shared hosting will suffice.

Required PHP extensions:

intl, gettext, mbstring, libxml, curl, gd (with freetype support), json, SimpleXML, xml, zip, sqlite3, pdo, pdo_sqlite

Recommended (additionally) shell_exec support (cutting panoramas on the server), ffpmeg (audio conversion) installed, exif extension (for automatic photo rotation).

The CMS4VR System works properly on the PHP version of minimum 7.4.0, but the recommended PHP version is minimum 8.0.

The CMS4VR system works in the cloud on the server where it is installed.

It can be your private server or your client.

The CMS4VR operation is fully automated and its operation is done with a web browser.

The server must meet the minimum requirements, which are best checked by sending a special php file to it.

After sending the file, enter its address in the browser's address.

More about checking your server parameters here.


The entire installation version of the system is located inside the INSTALL directory.

This catalog should be completely copied to the server in the place where the project will be created. The installation takes place in a few steps. It is easy and intuitive. During the installation process, you enter the most important data and licenses. More here.

This is not a required parameter, but it is very helpful because it allows you to convert any type of audio directly into the cloud.

You can record and send voice memos from your smartphone.

If your server does not support ffmpeg conversion and you can not enable it, all audio files must have the mp3 extension.

In this case, ask to enable this feature of your hosting provider. The shell_exec must be active.

If he can not do it, simply upload the panoramas in the zip file from your computer. More here.

You do not need to install any separate databases. The CMS4VR system creates everything by itself.

The reasons may be:

  • Your server IP has been added to the anti-spam list.
  • Your server has outdated security certificates.
  • Your domain's SSL certificate is outdated or inactive.
  • Your server's firewall is blocking the connection.
  • Your server's operating system is out of date.

Please contact your server administrator to fix this error.

Yes. First of all, when logging into the system.

This is to check whether the license key assigned to this copy of the CMS4VFR system is correct.

During installation, the connection between your server and our database, where your key is stored, is checked.

This is now standard procedure.

If, for reasons beyond our control, your server cannot connect to ours, you will receive the following list of potential causes.

  • Your server IP has been added to the anti-spam list.
  • Your server has outdated security certificates.
  • Your domain's SSL certificate is outdated or inactive.
  • Your server's firewall is blocking the connection.
  • Your server s operating system is out of date.

Please contact your server administrator to fix this error.

You need two licenses.
The first one is a license for the CMS4VR system, which you buy on this website in the BUY section.

The second one is the krpano license, which you probably already have (it can be purchased at

This license enables correct operation and display of panoramas without watermarks from the manufacturer of krpano technology.

The CMS4VR system to action is not necessary. However, without this license, all panoramas will have a special watermark.

For commercial and business purposes, you must have your own krpano license.

This is a license to the independent engine that powers the 360/VR industry.

You buy it independently.

The krpano license stays with you and you can use it in all other krpano-compatible applications available on the market.

When you update your CMS4VR system, you update everything, including the latest version of the krpano engine. Just like wordpress.

Only to manage the contents of the project as administrators or editors.

It is not allowed to transfer copies of the CMS4VR system to anyone else.

There are no such restrictions.

You can install your copy of the CMS4VR system on any number of domains.

After all you have or will have a large number of clients and each of them has its own domain and server.

If anyone tried to register your copy of the CMS4VR system license with a different krpano key and a different email address, the license was automatically blocked for security reasons.

In this case, the basic provision of the use license has been violated and it will not be possible to use the CMS4VR system.

Therefore, it is CRUCIAL to keep all license keys securely stored in a safe place. However, if this happens to you by accident, please contact us.

The security of storing the license key is the User's responsibility. One license of the CMS4VR system can be used by one user. In this case, please contact us. We will check where the violation occurred.
The first version of the CMS4VR system was officially released on February 6, 2016 at 5:57 p.m

The krpano key is independent of us and you can use it in other krpano based applications.

In the CMS4VR system, it is necessary for the correct operation of krpano tools (processing images on a server).

If you have a Standard license and have purchased the VIP version, you do not need to do anything.

Our system will automatically unlock all functions of the CMS4VR system that are available for the VIP version.

The update will work immediately ON ALL projects you have created under your license.

Yes. And we encourage you to do it. You only need a browser and internet.

However, we admit that it is more convenient to use the system on a computer.

You must add a user to your Amazon Polly account and download special keys that you enter in the CMS4VR system. You enter these keys in Amazon Polly options.

Go to Settings -> Amazon Polly and enter the codes. Save Changes. Then go to Languages -> edition and select the appropriate language from the drop-down list. Save Changes.
From now on, the "Get from Amazon Polly" button will appear in the add media window next to the text boxes.

You must send the file again. For security reasons, all links, links and POIs pointing to this file are automatically disabled so that there is no error in the system.

Use the password reminder in the login window. A link to change the password will be sent to the appropriate email.

Download the special droplet and place it in the krpano catalog that you downloaded from Then drag the panorama file to the droplet. After finishing the work, all files (except the panorama file) should be packed into the zip file. More here.

The CMS4VR system has been designed in such a way that you can build advanced virtual tour projects without knowledge of coding and programming.

Completely in the NO CODE model.

The CMS4VR system is extremely complicated from the programming side, therefore unauthorized interference with source codes may result in incorrect system operation. We do not recommend such action.

If you have any wishes or suggestions - write to us.

You may have the wrong password or wrong login. If you don't remember your password, generate a new one.

If there are communication errors between your server and ours, you will also not be able to log in to the system. This protection checks the correctness of the CMS4VR system license each time and is a standard anti-piracy protection.

It is necessary for the proper operation of the system.

The CMS4VR system contains the most modern and innovative solutions dedicated specifically for WebVR systems.

Your project not only displays panoramas in VR mode, but also correctly supports the entire navigation system, solar flares, 3D sounds and selected POI types, etc.

To some extent, the templates can be subjected to individual modification.

However, we recommend that you only add templates from our repository. In the future, the template system will be significantly improved.

To some extent, yes. However, this is a task for those who know the complicated syntax krpano.

Go to Settings -> Google Map and enter the Google API code. Save Changes.

Yes. Go to Categories and click on Panoramas from the selected category. You will go to the list of panoramas in this category and here you can move the panoramas up or down by setting their order. More here.

Search engine robots (e.g., index all relevant and important content, including their counterparts in links, graphics and multilingual content.

You can install additional, independent applications in the CMS4VR system.

Each of them is programmed to perform specific tasks and a defined function. Applications run outside the architecture of the main system, but work perfectly with it.

The application may have different functions and operation. See more here.

The VIP license users can use applications and games for free. Standard license users can purchase any application through this page.

All applications and resources are available in the DOWNLOAD section.

Different. From visual, through technical or functional. A full gallery of applications with a description of their functions can be found in the APPS&GAMES section.

VIP license users can use the applications from the moment they are installed.

Standard license users wait up to 24 hours from the time of purchase to activate the license for the purchased application.

After this time, the application can be installed on the system and used.

Yes. Our goal was to provide you with a business tool that will allow you to grow your business and earn money.

Yes. On as many as you want. Remember, however, that these are designs made by you under your license.
Yes. There is no limit. You can install your copy of the CMS4VR system on any number of servers.

Each project is completely independent and therefore requires the installation of a separate copy of the CMS4VR system.

Only in this way will your virtual tour be independent of other projects.

The installation is very simple and takes about a minute.

Yes. And it will remain so.

Therefore, it is worth purchasing a VIP license right away. This is simply a big saving of money.

It is a mathematical object that has defined boundaries, shape and space. It's a "virtual" box.

What is important is that each panorama can have its own tailor-made depthmap, which will not only add space to it, but above all ensure wonderful immersion in six axes (6-dof) on virtual reality helmets. This map will determine where in the visible panorama there are walls, boundaries, windows, objects, etc. And you will see it in 3D/VR space or with anaglyph glasses.

You will also be able to perform accurate collision mesh measurements on the panorama.
This is a wonderful innovation and a completely new dimension of the 360/VR world.

See our examples.

Some applications or phone models can do it automatically (with the Lidar function).

However, if you want to have a depthmap for your panorama, you can create it yourself in Blender or have it done by a specialist.

This is an extremely interesting and attractive type of view of a panorama or an entire 3D object. It resembles the view of a dollhouse, hence the name. See our examples.
Click this button that appears on the depthmap panorama

Standard license owners have a signature on each project that it was created using the CMS4VR system.

VIP license owners do not have such a marking.

The elimination of our branding in the VIP license applies only to the virtual tour interface. The backend is still marked with the cms4vr footer.

You have to answer this question yourself.

The Standard version offers several times more functions and possibilities than the most extensive and many times more expensive SaaS applications.

Read the feature description and make your decision.

So far, over 80% of our customers either purchased a VIP license immediately or purchased it shortly after trying out the CMS4VR system.

You pay for a Licence of the CMS4VR system only once and you can use it for a lifetime.

Yes. Under your license, you can create an unlimited number of projects.

But remember to protect your license key, because without it, the system can not work in the case of a leak your key to the internet, it can be deactivated.

All updates from a particular version (eg ver 1.0) are free and will be done will be done in one click.

All you need to do is submit a complaint procedure to the store where you purchased the license.

It's enough.

Resigning from the CMS4VR system license means that no projects created under this license will be available online.

Only two:
1. Deadline up to 30 days from the date of purchase.
2. Deleting all projects that were created thanks to the CMS4VR system.

Unfortunately not. The system is so cheap and offers several dozen times more possibilities than some SaaS models that we cannot afford such gifts.

Yes. All you need to do is purchase an update to your VIP license. Here.

For the VIP license only.

We can provide this in exceptional circumstances. In such cases, we divide the cost of the VIP license into 12 months and add a processing fee.
