Bluehost changed the MySQL version out from under me again, so I updated PhpBB to the latest version. Unfortunately, it's not compatible with the style (called "subsilver2") that we used to use, so I've picked out this new board style that's to my taste for now. Please let me know if you experience any issues or if the new board style causes any problems for you.
We also lost some customizations we had made, such as disabling of the BBCode button for font size. Please don't abuse this. I'll probably disable it again.
