After upgrading to 2.3.2 (from the initial 2.3 release) I notice that comments.php will... well, $user_ID does register, and $user_identity returns the correct name, but trying to post comments from a logged-in user gives me <b>Error: please fill the required fields (name, email).</b>
I'm not sure if this is a bug or not (I'm using Brian's Threaded Comments, tweaked to recognize logins), but I tried disabling it and reverting to the standard comments.php, which leaves the same problem.
As a hack, I'm trying to graft on some <input type="hidden"> tags to the login block to make it pull the information automagically. $user_identity is easy, but I can't figure out how to get $user_email - I tried value="<?php echo $user_email>" but that comes up blank for some reason.
Has anyone else come across this problem? If I'm alone, does anyone know how to finish my hack?
