Could be that too many people are using the site for the servers to handle. What I do is just take a "time out" myself and try later. It's one thing when you're just trying to view a page and quite another when you're trying to post. Chances are when poster is trying to post and they get the error, their post went through, but it just didn't display
for them...
then they hit the backspace and hit the submit button again; this is what gives us double & triple duplicate posts and threads. What cracks me up is some will go and make
one more post to apologize for the mistake when they could just edit the last reply.
So if you're posting and you get the error, backspace and copy what you just wrote, then
check in another tab or whatever for the thread or topic area
you tried to post in for your post, it
might have went through...if not, try again with your paste.
