Hello, thanks for your answer.
It work great, but now, when i try to edit something in admin panel, i have sometimes (random) error :
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, email@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
I don’t have access to the serveur log, i will try to find it but it’s not 100% sure.
The website is very slow since i move it up on the ftp.
Do you have an idea of what happen?
