So, I have trouble with the category pannel in the admin. An image is more efficient than word in that case, so here it is !
So I can't edit categories...
At first I thougt that "category icon" plugin was the problem, but deleting it doesn't help. I tried uploading the wp-admin folder again too. Can't find someone who had the same problem (and the french forum for WP didn't help).
So... any idea ? (kinda big problem in fact)
