I’m having a similar problem. When anyone tried to post a comment on my blog, they’d get a page of SQL errors instead of being able to post. Additionally, I’m getting comment notification email that request moderation, but the comment doesn’t exist (all the fields are empty).
I solved it brute-force method by commenting out the line in the Akismet plugin code that reads ” $wpdb->query(“DELETE FROM $wpdb->comments WHERE DATE_SUB(‘$now_gmt’, INTERVAL 15 DAY) > comment_date_gmt AND comment_approved = ‘spam'”);”
I picked that line because it was the first one that appeared on the error page. But I know that’s not the best idea. I hope others more knowledgeable know what’s going on.
