 "WPCasa  [9:50 AM]
 I am unable to work with WP 7.0 in Playground and with Firefox. It is not
 possible to add a new page, open the website editor, or edit styles. The
 message "Blocked page: Your organization has blocked access to this page
 or website" always appears. I have read that there was a chat about this
 topic previously, but I cannot find a ticket for this issue (in my
 opinion, it is a blocker). Did I overlook the ticket, or should I open a
 new one?"
