All of a sudden, when users try to comment on my blog they get redirected to the front page with this URL:
I haven't done any updates for a while and didn't make any changes recently to the db or code. I've checked plugins, comment pagination, checked permalinks structure and the comments.php. My form looks alright when I view source:
"<form action="http://www.MY-EMPLOYER.com/blog/wp-comments-post.php" method="post" id="commentform">"
But something's not working right. Has anyone else seen this?
