Troubleshooting Online Viewing
How to troubleshoot online tours
If the tour worked locally while building the tour but not after uploading, there was an issue either during upload or in the setting of your server.
  1. On the tour's direct page, open the developer tools of your browser (usually with Ctrl+Shift+I)
  2. Go to the Network tab and do a hard reload (Ctrl+F5) of the page
    • From there you'll be able to see if some files are missing or if they don't have the correct permissions to be accessed (they should appear in red).
      • If some files do appear in red, check they were correctly uploaded on your server and have the appropriate file permissions.
      • You will be able to compare the tours on your server and on your computer using your FTP Client (like Filezilla).
      • If you do not know how to find your files or modify the permissions, you will have to contact your hosting provider for assistance. Kolor does not provide web development and publishing or hosting services and as such can not offer technical support on this point.

My fullscreen button is missing
If your tour is included into an <iframe> tag, the allowfullscreen attribute must be added.
<iframe ... allowfullscreen="true" mozallowfullscreen="true" webkitallowfullscreen="true"></iframe>
Also make sure your browser is up to date, and see this page to see if your browser/device is compatible with the fullscreen API in the HTML5 player, because the button is also removed if it isn't supported by the viewing browser/device:

Viewing the tour isn't smooth
Tours built with v2.3 or lower:
This is due to the incorporation of the Flash Player and HTML5 plugins above it. To remedy this, try adding ?html5=prefer to the end of your URL. Doing this will force the viewer in HTML5 first, but have Flash as a fallback in case the browser does not support HTML5.
Rotation should be much smoother because there won't be the interaction between those two components.

From Panotour 2.5+, the HTML5 player is loaded in priority, so you won't need to add the code to the end of your URL.

Some plugins are not displayed or interfere with the fullscreen mode
Some browsers don't support the HTML5 fullscreen API (see
For these browsers the HTML5 plugins are not displayed in full screen mode. These browsers include IE and earlier versions, Safari 6 and earlier versions.

Tour and video (youtube, vimeo, dailymotion) in fullscreen concurrency
Panotour Pro generates a tour which is compliant with the Fullscreen HTML5 API. But the videos providers as YouTube, Dailymotion and Vimeo use also this technology to display video in fullscreen mode. So when using Video Fullscreen, the fullscreen event can broke the tour fullscreen until the video is closed.

Some plugins appear always over other plugins even with the plugins order have been defined
Yes, the HTML5 plugins are always displayed over the others plugins. You can order all plugins but the ordered HTML5 plugins will be always over the standard plugins. HTML5 plugins concerned are:

Tours made with Panotour 2.3 or under do not work in Microsoft Edge
It's a bug in KrPano HTML5 viewer, which is fixed in the version 1.18.5 of KrPano and the 1.19 pre-release 3. The fix is included in Panotour 2.5.
