The only plugins I have active are weighted categories 1.2 and WP database backup 1.7. When you leave your name with the comment you get a “no posts match criteria” and when you type only in the comment box you get a blank page. Strange.
I did also re-install wp-commments-post.php but alas, no fix.
I have a hunch that it’s my server, and of course my server (bluehost) will point the finger back to wordpress….
Any more ideas?
