I get occasional errors logging in. Invalid user ID or Password. Problem is, I see two different log in screens. One gives me the error and the other doesn't. I suspect what's happening is the forum is on more than one server. These servers are supposed to update each other with new info. It's called replication. But replication for some reason is not working properly or completely. Could be settings somewhere or could be corruption.
The issues mentioned here are two fold. For starters, you all have less than 10 posts so far so that portion of the error is correct. What is wrong is why the system is seeing you trying to post a URL. Bottom line is, Admins need to do some work.
