Removed old plugin installed with the module plugin gallery in origin (zip with plulgin and module), and replaced with this one:
1.0RC2++plug_cbprofilegallery(F).zip
Is the one you can download alone (not with the mod mod_cbgallery_1_2_RC2), only the file of the plugin the RC2SR1-(Fixed)
It works seems, i can add items.
I'll test it deeply later.
Now i must only resolve with the "one to one chat", that won't work, but this is another story.
Thanks !
