ok, let's get this cleared up.
in your database, in the config table, there is a field called "server_name"
when you are in the admin panel of your board, the domain name box is what affects that server_name field of the database.
if you put anything other than your domain name in that field you will have problems.
you can't put "localhost" , also, you can't put http://www
. in it.
the script adds http:// to whatever you put in that box, therefore , your IE browser will redirect you to micorsoft usually, but it may just give you a blank page or a page not found error, firefox will do the same thing.
therefore, don't put it into the box for domain name.
my comment about what is and what isn't a domain name is appropriate,
is not a domain name, it is a url
www is not necessary either, but it really doesn't matter if you use it or not as long as you are consistent.
now, if you read the complete post that I quoted, you will see that he tried several different things in the domain name field in his admin panel, none of them worked , for the reasons I have listed.
what part of this is not on topic or correct advice?
