Possible bug with directory index defaults
There might be another bug concerning the directory index defaults that get set when you create a web with a template. Shouldn't this be controlled by optionen_directory_index in the form ISP Web? There is no such option in the form ISP Web Template. That's why I assume it. So, I reduced the possible index pages in ISP Web optionen_directory_index, but nevertheless, each newly created web gets all the "default" index pages. It seems that is hardcoded in some php page or template and not in the forms editor.
