I suspect this has already been submitted and fixed in the CVS, but during my brief search I could find it (might I suggest a Search function for this to avoid so many duplicate submissions)

Anyway, clicking on any of the search links on the homepage a "General Error" comes up.

For "View unanswered posts", "View active topics", and "View new posts" the following error comes up:

SQL ERROR [ mysql4 ]

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 t.topic_last_post_time DESC LIMIT 1001' [1064]

SQL

SELECT DISTINCT t.topic_last_post_time, t.topic_id FROM phpbb_posts p, phpbb_topics t WHERE p.post_time > 1153670815 AND t.topic_approved = 1 AND p.topic_id = t.topic_id AND (p.post_approved = 1 OR p.forum_id NOT IN ()) ORDER BY t.topic_last_post_time DESC LIMIT 1001

And for "View your posts" the following comes up:

Again, I suspect this has already been deleted but here it is anyway.
