Hi,
i am using Plesk Onyx 17.5.x and would like to ask, where i find the Template Files like the on in attachement.
Moreover is this possible to modify for each Customer (if the customer wants to) ?
Cause in the errordocs of Customer, theres the "old ugly white" Page.
I have that activ, i also have it active within Customer Area in the Hosting Settings.
What am i missing? do i really have to insert those docs in the additional directive?
