Thread:Project:Support desk/Unable to upload new version of existing file

We're getting the usual "Could not rename file" error when trying to upload the new version of a file, but it's ONLY with files that have been uploaded prior to our last wiki software upgrade (around 9/13/2011... 1.13->1.16.5). We can easily upload duplicates/updated files to any file that was uploaded once the update was made, but any file uploaded prior to 9/13/2011 cannot be moved to the /archives folder.

Have checked all the directory permissions and can't find anything wrong. (We're using Windows Server 2003 with IIS, in this case the IUSR account has modify permissions on the entire /images directory as well as images/archive.)

MediaWiki version: 1.16.5 PHP: 5.2.17 (ISAPI) MySQL: 5.1.58

Keep in mind we're on a government network, so don't chastise us too quickly for having an outdated version of PHP/MySQL. ;)

Hallllpppp! -Kendall
