You say "some users"... have you identified anything tht could be different for these users ?
Does it reproduce on other browsers ?
Does it happen only for month scale ?
It happen for every scale not only the month on IE but not on Chrome.
The problem appears just after the upgrade to v5. The user are all "project manager". when they connect to ProjeQtOr on my computer no error display.
When I connect on their computer same error appears
If issue is not reproduced on your computer with same OS, then it is very likely a browser issue.
Are you sure you completely cleared the cache. F5 is not enough on IE.
You must go to advanced parameters to clean the cache.
Also, do these users have special browser extension ?
For instance, Skype "click-to-call" extension is known to set a mess in the application.
I found a solution: delete the folder Temporary Internet Files in C:UsersxxxxxxAppDataLocalMicrosoftWindows
It's a bit radical, but it works.
An d it confirms it is a browser cache issue.
