Thread:Project:Support desk/Invalid url gets redirected to a different wiki folder

MediaWiki(1.18.0) PHP (5.2.3) MYSQL (5.0.24) http://www.derivative.ca/wiki088/

1) Above url was created/copied from http://www.derivative.ca/wiki077/. Each has a different database.

2) When you go to an invalid title page in /wiki088/, for example http://www.derivative.ca/wiki088/index.php?title=InvalidTitleName

3) it gets redirected to /wiki077/ search page at http://www.derivative.ca/wiki077/index.php?title=Special:Search/InvalidTitleName

I've checked the /wiki088/localsettings.php and there is no reference to wiki077! I've also looked into the help and documentations but no luck. Any ideas would be greatly appreciated.

Thanks.
