Can't select one project

[JPOL]

After upgrading from 1.0.3 to 1.1.8, I can't select one project in the project list of the main screen : after selecting another project, it return to the user default project. It's always the default project of the user which is selected. Any idea ?

You must clear all cache data.

I clear the cache, but I've the same thing. I test on Opera, Chrome, IE7, XP and Vista.
Another idea?

The problem is solved : we only upgrade php from 5.2.10 to 5.2.3 and it works fine !
