Thread:Project:Support desk/File Upload Error/reply (6)

So, here is what finally fixed it for me:

sudo mkdir /var/www/html/mediawiki-1.24.1/images/temp chmod -R 777 /var/www/html/mediawiki-1.24.1/images sudo setsebool -P httpd_unified 1

The last command was suggested by the log dumped to screen when you run

audit2allow -a -w

So I guess it's SELinux. I will try to see if it stick after a reboot. I hope this helps somebody.
