Hello ISPConfig community, Yesterday I added a new "slave" server to ispconfig. So now I got my first ISPC3 server as master, and a second server to a single customer. But since yesterday I have several times faced that when i try load pages in ISPC3 control panel, it doesn't load. If i try press F5 to refresh i get following error. Forbidden You don't have permission to access /index.php on this server. Does anyone know, how I solve this problem?
