This is the problem with using sharware, when servers are updated for better performance it takes along time for the phpBB minions to upgrade their side, and as a lot of forums have found out it's not back compatible. Like so many things, life gets in the way, and you need more than one full adminwith FTP rights to run one, I can appreciate that it's Eds baby, and he wants to keep it that way, but as I found out, you have outside pressures as you get older, like work and family, and the forum takes a back seat.
There are options;
Start from scratch.
New Admins with FTP rights, new platform, new server. ( Ed owns the domain United Rant) So it would have to be new name.
Persuade Ed to hand over rights to this board to someone he trusts (?)
Wait until Ed fixes this one, but it seems that either he doesn't have the time, or phpBB minions can't fix it without reqriting the whole script, which could take a long time.
Take all the courage you have left
And waste it on fixing all the problems that you made in your own head
