I see that, if you look at your post here:
on our test boards
It works.
This is the maddening thing, except for it having newer posts that board is identical to here, and it is running 3.1 no problem!
I have asked what would be required to copy all files (except our downloads and gallery of course) and database entries from the test site to here.
No response yet, I guess they are very busy now with others having upgraded too.
Sessions seem to time out a bit quickly here too, I found myself logged out again after being on another site..
