Since upgrading to 2.7 on all of my blogs all comments for all posts are going directly into moderation. On the Discussion settings page both of these options are unchecked:
An administrator must always approve the comment
Comment author must have a previously approved comment
I have also read other threads regarding commenting issues recently but the solutions to them have to do with commenting not being allowed at all. Like the solutions to these threads:
http://wordpress.org/support/topic/205781
http://wordpress.org/support/topic/212276
http://wordpress.org/support/topic/215579
This is affecting all current posts and any new posts I do. The only correlation I find is that on all of these blogs I had been using a beta version of 2.7 before it went final. On the one blog I went directly to 2.7 final the commenting is working. I have tried exporting the posts and comments then deleting all of the tables and reimporting the posts and comments after reinstalling Wordpress and the issue still exists.
Any ideas?
