When I post a message, I get a "Query Error" message and my post doesn't get posted.
This is due to the website being worked on... The server "updates data" and yours gets lost in the process. If you wish to post a long message, I would copy the text first so you don't have to re-type it all. That is what I do.
Thanks for the info! It seems to be rather random.
It usually happens when the site is being upgraded.
I really do not know exactly. Maybe the request made was not understood by the website.
