Hi there,
I have been getting this message for a while. We hope we have not lost our forum!

Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later.

that would be an issue for your host to look into, smf is just telling you there is a problem. who is your host?
my host is midphase.com
they are an oversold host, if you move to a better non-oversold host you will find most if not all your problems go away.
