Same problem here. Have re-installed the script files, and have used several themes including the defaults. Have made it as easy as possible for someone to post — no limits. Have tried to post as admin and as a registered user.
An original posting is accompanied only by a “0 comments” link. Click it and you get a comment posting box. Fill it in and submit, and the page pretty much recycles.
Have never been able to see a comment, or get one recognized by any part of the management console.
Spen a lot of time learning the new design features; never thought a problem like this would make the blog unusable.
Help would be nice… but I see a lot of other folks are stumped.
By the way…. is it possible for a registered user in this discussion forum to change his password?
