I'm working for a french psychologists association. We have two different worpdress sites.
The two are hosted by the same hosting company ("Netissime").
Until a few days ago, it was possible to upload a file in the library very easily.
Bu since a few days, it's impossible to upload a file with the "add btton" in the library for the first one. The second site allow perfectly to upload files with the add button.
This is the WP configuration for the number 1 (the one which have a problem) :
Installed and activated plugins : Contact Form 7, Event Calendar, Simple Press Forum, User Access Manager, Zerby Login Widget
The difference with the other site on the same Host are :
There is no the "User Manager Access" but I attempted to disactivate it on the first site ( the 2.8 version one) and there is no change.
Is someone has an idea ?
