Myphone local installation shows white page

[Desort]

Hello folks,

starting a few days ago I'm facing a problem with the local installation of our 3cx myphone applications.
On some of our Windows PCs it only shows an blank page without any controls. Right click show the "Silverlight" menu.
Starting the application in an IE window using the servers URL works fine.

I was able to fix it by removing the myphone application, deinstalling/reinstalling Silverlight and reinstalling the local 3CX myphone application. But on the next day the local application once again shows a blank window.

I know that this is a Silverlight issue, but I can't find any solution on the web that fixes my problem.
Maybe some of you experience the same issue and already found a solution.

We are using:
3CX Phone System Version 11 SP 1, Build 27011.711
Internet Explorer 11

A little bump.

Problem still unsolved :cry:

Hi,

If you are running this 4 yrs old 3CX version, why not with the latest available Service Pack?

I don’t know if IE also can cause the issue, but have you tried FF or GC?

Sorry, no idea where I found this old release number.

The installed release is:
3CX Phone System Version 11 SP 4B, Build 28976.849
