I tryed to find someone with the same issue here but no success.
It happens with almost all of my users, including me.
When I take too long to post a reply, I get the insufficinte permission message, and after come back to the post page I have our message erased.
Considering that, if I take too long to write a message, usually it is because it is big, so I it very annoying to notice that you lost every word you wrote...
some users asked me if the is related to the size of the message, but I tested and it is possible to post it back again if I save it before. And I also tested with a small text, after some wait an it did the same thing, so for me it related to the waiting time until you post.
Is there a way to solve this issue?
Thanks
