I don't know how to change the problem with ftp.
I've created a new user ftp with ispc config and when i try to connect with fillezilla :

Code:

Échec de la tentative de connexion avec "ECONNREFUSED - Connexion refusée par le serveur".

 

Hi!
Because i can't to connect by sftp with wordpress, i must have ftp service running could you help me please?

Ps: i've followed this tutorial for installing ispconfig :
https://github.com/servisys/ispconfig_setup

PS: i answer "no" to use quota on this server. Maybe this could lead to this bug?

 

Some logs if you can see the problem :
