Hello everyone
Following the answer of our friend Klaus started here and in order not to polluting the original thread I am trying to get help in the right thread I hope, I have just made the encryption test of my .xml files only via Krpano Tools. And it turns out that it does not work correctly either locally or online, let me explain I created a description of the site of the visit and when I encrypt it, I click on the "i" icon "Small history" the window opens but it is empty with the title "Undefined" and the closing cross has disappeared (on the display of the map, the problem is the same with the title, but the map displays it well). I think other files should be encrypted with it, but the problem, I don't know which one !!
A link to the encrypt with Krpano Tool test visit:

Thank you again for your help
Good evening and good weekend to all
