I've been seeing the above message occasionally when I attempt to post messages on a wikia. It is apparently satisfied with a page-refresh, but the content of my messages are gone. So far as I can see it happens only on the one wikia.
Before I take it to S:C I want to find out if anyone else is encountering this?
