Thread:Project:Support desk/File Upload Problems, 'Could not create directory ...'

Hello, when I attempt to upload a file to my wiki, it gives the error 'Could not create directory "mwstore://local-backend/local-public/c/c4".'

I am running MediaWiki 1.24.2 with PHP 5.4.38 (cgi-fcgi) and SQLite 3.7.7.1 on a shared server. The images/ directory has 0755 permissions, but file uploads do not work with 0777 permissions either. The images/ directory is owned by the same user that owns and (to my knowledge) executes the scripts. The php.ini directive file_uploads is set to "On".

The wiki itself is located at wiki.liamscode.net.

Before, I had used an (outdated version of) MediaWiki installed using an automatic installation script and file uploads were working fine, and the permissions of the (sub)directories seem to be the same.
