Thank you for your reply Till.
I'm still a little confused. Once I've changed the settings back in Apache, how do I go about setting up my site?
I'd like it set up so that I can access my site through my.domain, and access mail through my.domain/mail, if that is possible?
There aren't any jobs in the jobqueue, and there are no errors in the system log.
I also did not edit any settings within the system . server config.
Also, how would I go about setting up mail accounts once all the rest is set up?
Thanks again, it is very much appreciated.
