Comment posting error: Unknown column ‘ID’ in ‘where clause’

I’ve been running WordPress for several years on tons of sites, and this problem just showed up after I installed some more plugins on one of my bigger sites (1700+ posts, 18K comments). When a new comment is posted (whether I’m logged in or not), I get:

WordPress database error: [Unknown column 'ID' in 'where clause']
SELECT * FROM wp_comments WHERE ID = '18686'

WordPress database error: [Unknown column 'ID' in 'where clause']
UPDATE wp_comments SET comment_content = '' WHERE ID = '18686'

In this case, 18686 is the comment ID.

The comment is posted successfully if you hit back and refresh the page, so I don’t know what this error is referring to.

Any ideas? I’m using these plugins:
Ultimate Tag Warrior
CG-Amazon
LMB^Box Comment Quicktags
Never Moderate Admin or Post Author

RunPHP
Scripturizer Remix
Spam Karma 2 – Reloaded

Thanks!
