These are all new to the 2.1 upgrade. I have validated the page at this address
so i know that isnt my issue.
In firefox only!! tested with firefox and IE6. When I am logged into the admin panel the left sidebar and main post columns will not load, when i click view site, and also if i open the site in another tab or window. it only shows the right sidebar. not sure if it does it to others, but definitely to me.
Also noticed that clicking a post's "no comment" link will display this:
in the address bar but wont display the actual page to leave comments
It also does not display correctly in IE6.
