Thread:Project:Support desk/MediaWIKI 1.21 cannot import file PHP WARNING wfMkdirParents (2)

Hello guys !

I saw many posts about this problem, but even if I try change permissions (777 or 755) or change owner (apache) of my "images" folder, the following error appears :

"[Mon Jun 03 11:36:25 2013] [error] [client X.X.X.X] PHP Warning: wfMkdirParents: failed to mkdir "/wiki/images/5/56" mode 0777 in /path/to/my/folder/mediawiki/includes/GlobalFunctions.php on line 2582, referer: http://X.X.X.X/mediawiki_pro/index.php/Sp%C3%A9cial:T%C3%A9l%C3%A9verser"

php.ini : file_uploads = On => OK | ;upload_tmp_dir = => not set | ;open_basedir = => not set |

Could you please help me ?
