Thanks for the tip, Mark. I couldn't find anything obvious in the
settings table, however, using the MySQL Query Browser, I tried to find
any other tables that seemed mythweb related...
In the "mythweb_sessions" table I found a row that corresponded to my
user ID. I deleted the row, and now I can login to mythweb again.
The setting that got me into trouble in mythweb in the first place was:
Settings->MythWeb->MythWeb Defaults->Enable a cache engine?->Unix Shared
I won't be choosing that setting again!
