So I've set up and configured WordPress on an Ubuntu home server. I have a domain name and everything seems to be working fine with one exception. Though the domain name shows in the browser of the WordPress home page (e.g. http://www.blahblahblah.com) whenever I click on one of the links within the same page (WordPress login for instance) the IP of my server shows in the browser (e.g. http://xx.xxx.xxx.xx//wordpress/wp-login.php). I've followed various tutorials etc. but haven't yet solved the problem.
Does anyone know how I might solve this?
