Make sure your wp_usermeta record for that user has something like this:

meta_key=wp_capabilities
meta_value=a:1:{s:13:”administrator”;b:1;}

Please note the wp_ portion of wp_capabilities must correspond to your $table_prefix value in wp-config.php.

Thnx! Doesn’t really work for me. I looked in PHPmyAdmin and I have user_status set at 10 in wp_users. Also, in wp_usermeta I have wp_capabilities set at a:1:{s:13:”administrator”;b:1;}

Michael, the last part of your advise “…the wp_ portion of wp_capabilities must correspond to your $table_prefix value in wp-config.php” is not clear for me. Should I do what exaclty to check on that?

Thank you all
