Thread:Project:Support desk/Error uploading files

MediaWiki 1.23.0; PHP 5.3.24 (cgi-fcgi); MySQL 5.5.33 ;

OS windows web server 2008; Upgraded from Mediawiki 1.21.1

I receive the following error trying to upload a pdf file "Could not store file "C:\Windows\Temp\phpC378.tmp" at "mwstore://local-backend/local-public/8/80/TourismAct.pdf". It appears to create the temp file on the server under $ip\images\temp but does not rename and move the file to the directory. If I rename the temp file to pdf the file displays without any issue. So it appears as if the file is being uploaded correctly to the server.
