Look. If you're going to attempt to reopen the archive, then don't try to glue together the pieces that locoindigo and whoever else left behind. You shouldn't be attempting to run Yerf when you don't even know where you stand or why things keep crashing. Start over, if you must do this. Rebuild the code from the beginning with documentation, so that nothing about it is a mystery.
Better yet, accept the fact that Yerf's lost most of it's userbase, leave it open as a static archive for historical purposes, and retire. It's never going to be what it was again.
