Thank you for your response but unfortunatly it wasn't a problem due to the file access...
However, thanks to the website staff, I have the solution. If someone has the same issue, here is the solution :
The temp folder of the server was not in rw acces for some reason, so I had to go to phpdocx/config/phpdocxconfig.ini and change the "temp_path" to an other I've created.
Everything works fine now and the framework is amazing !
