phpBB : Critical Error

Hi,

I have a real problem with my PHP database.
It was working at about 9pm UK time.

But now when I go to where my forum should be I see

Could not connect to the database

I would really appreciate any help with this,
Many thanks,
Philip Orchard

Try posting that in the PhpBB 2's forums, most likely they have a topic for that, plus Ive seen that error in many other places.
