I recently moved my MediaWiki 1.5.3 database from a MySQL 4.0 server to a MySQL 4.1 server. OLDPASSWORDS is enabled, and PHP 4.4.1 is using the newest MySQL libraries. I am concurrently running a Simple Machines Forum (which works flawlessly, showing that there is no problem with password hashing on MySQL 4.1)
After transfering to MySQL 4.1, all pages are returned blank (<html><body></body></html) after an excessively long load time. I've tried upgrading to 1.5.5, and even running a fresh install of 1.5.5, all to no avail. During the install, the 'Initialising "MediaWiki" namespace' step takes excessively long.
I have no access to my PHP error logs, because my host (servage.net) is about as poor as they come when it deals with customer service.
Any help on this issue would be GREATLY appreciated.
