hello,

when trying to post a question with a registered user it shouts about permissions.
I have already checked all of the permissions given all to every kind of user.

what am i doing wrong ?

EDIT:
I have uninstall and install several times , removing data from the database manually all without success.

a guest can write questions no problem.
admin can without problem.
only a user cannot see into question and cannot ask one.

and by the way, you still write in the log that the comp' is version 1.5.4.
