Re : Rescue Tiki Install! (was: Internal Server Error)
You can take away a displayed module by removing the line in tiki_user_assigned_modules (name = module name)
You can play with local.php like you did. But the 2 tiki versions must have the same model (otherwise you have to run db/tiki_1.8to1_9 to go the upper version and you can't go back) You can check if the 2 versions are identical by comparing db/tiki.sql in both. Verions is not 1.8 or 1.9 but it is the cvs date ....
