I currently have wordpress installed on EC2 instance with an elastic IP. I have route 53 setup for an existing domain with a type A record set pointing to the elastic IP.
When I access the domain name in my browser, some of the web resources (js, css files) being loaded by the browser still point to the old public dns (ec2-x-xx-xx-xxx.<zone>.compute.amazonaws.com), so they fail to load and the site does not fully loaded. How do I fix this?
I found the solution here. Under the section 'Help! My Public DNS Name Changed and now my Blog is Broken'.
The reason I was having this issue in the first place was because I switched my EC2 IP to elasticIP after I installed and setup wordpress. So wordpress had the old IP in its installation. If I had setup the elasticIP before installing wordpress I would not have had this issue. But the above the link helped me solve it.
