I've been seeing a very strange problem with v1.5.1.x Whenever my site receives a pingback or trackback (sending them work sfine), they never show up. However looking through the logs and the database, the comment for the ping or trackback IS created in teh system but then, for some reason, its deleted. Why would it do that?
When I got an email indicating someone had pinged or tracked a post, I couldn't figur eout why it wasn't showing up on teh site. The email showed anew commetn ID had been assigned, even provided a link to delete the comment. Spam Karma 2 logs showed the comment had been processed and approved with flying colors (I disabled SK2 and the same thing is happening) If I look in the database in the wp_comments table - I can see the auto_increment counter incrementing with each comment. So for an instant - the comment is created in the database, but is then immediately deleted and there is no trace of it anywhere. I don't have any other spam prevention plugins enabled. I can't figur eout why this would happen. I've checked my options in the Discussion section - nothign seems like it woudl make WP do this. Has anyone else seen this behavior? Normal comments that you post from teh entry are handled just fine.
