Thread:Project:Support desk/File /home/users/mywiki/skins/monobook/headbg.jpg is not within the allowed path(s) (2)

I have the following warning displayed in my log each time a page of my wiki is displayed: [error] 202#0: *246 FastCGI sent in stderr: "PHP message: PHP Warning: file_exists: open_basedir restriction in effect. File(/home/users/mywiki/skins/monobook/headbg.jpg) is not within the allowed path(s): (/srv/http/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps) in /srv/http/mywiki/includes/resourceloader/ResourceLoaderModule.php on line 509

I understand the error: the file « /home/users/mywiki/skins/monobook/headbg.jpg » doesn't exist. But I don't understant why my wiki tries to get this file with this wrong path (/home/users) instead of « /srv/http/mywiki/skins/monobook/headbg.jpg »

Does anyone have the same problem ? Or know what could I do to fix it ?

I use Mediawiki version 1.22.5 PHP version 5.5.12 (fpm-fcgi) on Nginx I installed those extension SyntaxHighlight (version 1.0.8.11), FooterManager (version 0.0.1), GoToCategory (version 1.0), WikiEditor (version 0.3.1)
