 * I tried adding a subdomain to my existing domain [http://www.goodchoicesnoregrets.com](http://www.goodchoicesnoregrets.com)
   and i uploaded all of the wp files to the subdomain but it wasnt working i than
   deleted the subdomain and all of the wp files but now my original domain is not
   wokring. When i go to the original homepage it says:
 * Warning: require_once(admin.php) [function.require-once]: failed to open stream:
   No such file or directory in /home/mccall/public_html/index.php on line 3
 * Fatal error: require_once() [function.require]: Failed opening required ‘admin.
   php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/mccall/public_html/
   index.php on line 3
 * I can see that the admin.php file is there and i even uploaded it again but it
   is still saying the same thing. I have know idea what to do?
