My sincerest apologies for the recent forum downtime!
It took a few days for me to notice, and then it took a few days for me to find it.
Apparently there was a non-critical database failure, which was easy to fix, but phpbb had cached an invalid, empty white page, and it took me quite some time to figure out that that was the cause.
So again, I'm sorry. Please flock back to this forum, and tell your friends who may have lost their way
