Thread:Project:Support desk/Cannot upload Image

I've installed Mediawiki v1.24.1 on my server which is running RHEL7. I've installed it under /var/www/foohelp/wiki. However, when I try to upload a file, I get the following error:

[f3eae72a] /foohelp/wiki/index.php/Special:Upload Exception from line 1871 of /var/www/foohelp/mediawiki-1.24.1/includes/filerepo/file/LocalFile.php: Could not acquire lock for 'User-default.png.' Backtrace: If I edit /includes/filebackend/FileBackendGroup.php and modify LockManager to

'lockManager' => 'fsLockManager', and modify permissions as follows:

chown -R apache:apache images/ chown -R 755 images/ I get the following error:

(Could not create directory "mwstore://local-backend/local-public) Any help would be appreciated.
