"web/Main" is an invalid name for a new web

You are recommended to choose short names, preferably less than 10 characters, starting with an upper-case alphabetic character and using only alphanumeric characters. If you want to create a template web (a web just used as a base to create new webs) choose a name that starts with an underscore and has only alphanumeric characters.
