Serious db problem:You have an error in your SQL syntax near \'ON id=mesid WHERE userid=62 AND name=\'admin\' AND email=\''asdqwe@mail.ru\' AND s\' at line 1 SQL=SELECT id FROM jos_fb_messages JOIN jos_fb_messages_text ON id=mesid WHERE userid=62 AND name=\'admin\' AND email=\'asdqwe@mail.ru\' AND subject=\'ertertert\' AND ip=\'127.0.0.1\' AND message=\'rftt\' AND time>=\'1210591804\'

это
$database->setQuery("SELECT id FROM #__fb_messages JOIN #__fb_messages_text ON id=mesid WHERE userid={$my->id} AND name='$fb_authorname' AND email='$email' AND subject='$subject' AND ip='$ip' AND message='$message' AND time>='$duplicatetimewindow'");

на это
$database->setQuery("SELECT id FROM #__fb_messages LEFT JOIN #__fb_messages_text ON #__fb_messages.id=#__fb_messages_text.mesid WHERE userid={$my->id} AND name='$fb_authorname' AND email='$email' AND subject='$subject' AND ip='$ip' AND message='$message' AND time>='$duplicatetimewindow'");
