After migrating from 5.0 to 6.2.4, we are unable to add new users.

When we click on add new, the page is half loaded, and seems to be stucked at the timezone (we do not have any params after timezone - see in img attached).

The problem is the same on this pages :

• When a user wants to edit its profile
• On Administration > General > GUI

Thanks you for your help.
