I have two plugins that don't seem to want to play nicely together.
Sideblog: http://katesgasis.com/2005/10/24/sideblog/
UTW: http://www.neato.co.nz/ultimate-tag-warrior/
Latest version of each.
In general, all seems to work just fine. However, it all goes pear-shaped when clicking on a UTW tag. What's supposed to happen is you get a list of all the posts with that tag. Instead, now I get a 404 and SQL Errors like:
WordPress database error: [Unknown column 'category_id' in 'where clause']
SELECT DISTINCT * FROM wp_posts INNER JOIN wp_post2tag p2t on wp_posts.ID = p2t.post_id INNER JOIN wp_tags t on p2t.tag_id = t.tag_id WHERE 1=1 AND post_date_gmt <= '2006-05-23 14:25:59' AND (post_status = "publish" OR post_author = 1 AND post_status != 'draft' AND post_status != 'static') AND post_status != "attachment" AND category_id != 18 AND t.tag IN ('gliffy') GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 7
Disabling Sideblog cures that.
Tried leaving some comments for the sideblog author (and I see some others have the same issue). No response.
Curious to see if anyone else has fought this battle -- and if so, looking for ideas on how to resolve it.
