Hi-- I have been encountering a consistent error when trying to install mediawiki 1.8.1 on XP SP2. I unistalled and reinstalled my PHP, mySQL and Apache and updated all files, and the error continues to occur. I also dropped the wiki db to retry and disabled windows firewall, but that didn't help. I have found several reports of other encountering this error, but found no solution and nothing in the help pages regarding it.

Any help much appreciated. Error message below.
