It's the second time it happens...first time I simply reinstalled everything.

I already checked some FAQ about checking the user and group_permissions in the database, but everything seems ok there.

It happened after having copied some tables using phpMyAdmin, apparently nothing to do with the admin/users/groups....

I can login using webmasters id and password, I get the administration menu, but once I click on it I get the "you have no right to access... " screen!

Any hint and help is welcome.

Ciao guys.
