Ok, still no luck with the comments. I got the page to load data lastnight, but at that point it wasn’t inserting the comments into the database. I downloaded the latest development release of WordPress lastnight from Subversion and copied the wp-comments-post.php page to my working WordPress directory, but that didn’t fix anything. I then copied the relavent functions.php file from the devel trunk, and then WordPress ceased to function at all.
I’m not even sure if it’s an error on the wp-comments-post.php page or if it’s in one of the functions…I almost think it’s in the function that’s used to insert data for a comment.
