[TurboGears] Unrecover after a crash

[icylamb]

  Hi all,
 I ran across some 500 internal errors when building my wiki. It's
funny even when I changed back to what I had before the error happened,
restarted the server, drop the database & build the new one. The error
is still there! ic... anyone had this problem before? Do you think this
type of error is cached? please help.
