I have been reading through the posts and tried to solve this problem. Unfortunately after the modification of a site, ISPConfig seems to be writing in the backupfile instead of the correct one. A new file named Vhosts_ispconfig.conf_31-05-07_14-49-38 was created and has the new settings whereas the file Vhosts_ispconfig.conf is older and has the old settings. Has someone experienced this problem before? I am using the latest version of ISPConfig.
