Syntax error on line 615 of
'etc/httpd/conf/httpd.conf:615: <Directory> was not closed
As for your httpd.conf error, you need to stop trying to fix it with workarounds ie changing the domain name, as whenever you try to make other system changes, an error reappears.
Concentrate now on the source of that problem and fix it.
Did you look in the file referred to, what does it say on that line number ?
Is there anything you (unwisely) did to your server to cause that problem, you seemed to say you did something before. It is easier if you tell us what you did and then we can tell you how to undo that, ie put it back to normal.
You were given some instructions earlier, so please follow them, rather than going off doing your own thing, and prolonging the process and using up more of our time unnecessarily.
