Thread:Project:Support desk/File Upload Error message

I just installed Mediawiki 1.23.1 on a Ubuntu 12.04 LTS server.

I followed the steps exactly on the mediawiki site.

I used WGET in order to pull the .tar.gz file to my server from mediawiki's site. I then moved the mediawiki folder from " /home/user/ "  to " /var/www/ " which is where the index.php file resides and then placed the LocalSettings.php in the mediawiki folder.

When I browse to my wiki and try to upload a file, I get the following error message: " Could not create directory "mwstore://local-backend/local-public/8/83"

How do I fix this?

I cannot post my wiki url because it is a private wiki and you would not be able to browse to it I don't think.

Please Help!

Thank you
