Hey John,
Sorry about that bug! I remember few days ago reading a tweet from Nicholas complaining that the js for the adminForm has been changed between the beta and final release and back then I didn't think that it affect us... but obviously I was wrong...
So, the fix is really easy!
Go to administrator/components/com_comment/views/comments/tmpl/default.php
on line 36 you will find this code:
<form action="" method="post" name="adminForm" >
change it to
<form action="" method="post" name="adminForm" id="adminForm">
And it should start to work properly again.
Cheers,
Daniel
P.S. About the problems with the ticket system - could you please check again? Logout and login into the site - your account permission are correct so you should have access to that section and you should see the CompojoomComment category in the ticket system. Thanks!
