[Mediawiki-l] install errors v1.8.1

[Dougie Fresh]

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.
