Plugin install

EN

Whenever I install a Plugin I get the usual error.
The strange thing that the plugin going back to the previous page through Broswer the Plugin I find it installed regularly ready to be activated, why?
Error:

WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ORDER BY pid' at line 1 for the query SELECT * FROM _prs_67_appromag_photos WHERE pid = ORDER BY pid made by File_Upload_Upgrader-> cleanup, wp_delete_attachment, do_action (' delete_attachment '), WP_Hook-> do_action, WP_Hook-> apply_filters, Profilegrid_Group_photos_Public-> pg_delete_attachment, Profilegrid_Photo-> get_photo_details, PM_DBhandler-> get_all_result

Ogni volta che installo un Plugin ottengo il solito errore.
La cosa strana che il plugin tornando indietro alla pagina precedente tramite Broswer il Plugin lo trovo installato regolarmente pronto per essere attivato, perchè?
