Hi. I've just recently installed ISPConfig 3.1 on a debian 10 server running nginx. I figured out that I can set specific directives for individual sites by using ISPConfig control panel. But how can I add the private folder to the PHP include_path for each site as a base config? It should be doable in php.ini, but what is the proper syntax to include the private directory from each web root? When I set up my web pages, I only have a single file in the public_html directory, everything else is located in the private directory. I'd like to do my includes without risking accidentally revealing any information about the directory structure.
