User Directories Map To Ip Address Not Domain Name

I recently updated my Domain name from my ip address to a domain I purchased on NameCheap. I had previously had user web directories set up and they would map to myIpAddress.com/~userName/file. If it I type in my new domain name it works, but I get a cross-origin No Access Allow Control Origin error in my console. Also, when I click a link it automatically maps to my ip address, not the new domain name. I’m using Wordpress as development. I want my links to map to the Domain Name not the IP Address and I’ve tried adding 'Header set Access-Control-Allow-Origin “*” to my userdir.conf file in Apache2, but no dice(Yes, I’ve restarted apache). Side note, I do not get the error when I’m loading my IP Address and the user web directories as the URL.
