Problem to refresh a webpage on the client

I have a problem for refeshing a webpage, normally every 20 seconds the webpage switch to another picture but on xibo it hang the same page is displayed … i have the version 1.7.8 of the client and IE 11.

How is that webpage doing the refresh?

Perhaps you can try with a different version of IE by changing the embedded browser settings as described here: Enabling HTML5 in the Windows .net Player

I have put already this registry key ( i have tested with IE 9 and IE 11)
the webpage works fine with the simple link but not on xibo.(it has some latency or hang)
I did this tutorial for the webpage (sorry it’s in french)
