Thread:Project:Support desk/Uploading Permissions

Running version MediaWiki 1.16.0 PHP Version 5.2.9-0 Running SUPHP OS: CentOS 5.5

Mediawiki is uploading files just fine, though when directories are being created they are created with permissions of 700 and when files are being created as 600.

Is there any way to specify that directories get created as 755 and files as 644?
