This is a server side issue with the folder pemissions or the addition of a add on to the forum. This is not something that us mods can fix. It is something that Larry is looking into. If you read the Rules and Announcement forum you will see all of the issues are already known and being worked on.
There are issues of health for Larry which is why he can not be focused on doing this and this task only. Which is why it is taking so much time to fix such a "small" issue. We dont ask for much we ask for some patience. As was explained in several threads already which could have all been found by looking thru the forums or with the search feature.
