eh, ho fatto come mi hai indicato, ma no cambia purtroppo.
..ho allora messo in debug il sistema e mi presenta degli errori che riporto:
500 - JDatabaseMySQL::query: 1064 - 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 'AND video.published = 1 AND video.approved = "yes" ORDER BY video.date_uploaded ' at line 1 SQL=SELECT DISTINCT video.*, u.name, u.username FROM jos_hwdvidsvideos AS video LEFT JOIN jos_users AS u ON u.id = video.user_id WHERE video.category_id = AND video.published = 1 AND video.approved = "yes" ORDER BY video.date_uploaded DESC LIMIT 0, 1
mah, la questione sembra più complessa del previsto.
magari provo a ricreare le categorie video..
grazie ancora
