WordPress Page Not Found on AWS: Troubleshooting and Solutions
Problem: You've deployed your WordPress website to AWS (Amazon Web Services), but when you try to access it, you're met with the dreaded "Page Not Found" error. This can be incredibly frustrating, especially if you've followed all the standard setup steps.
Rephrased: Imagine building a beautiful house, but then finding out the front door doesn't open. That's basically what happens when your WordPress website on AWS is stuck in limbo, refusing to be seen by the world.
Scenario & Code:
Let's say you've successfully set up your WordPress website on an EC2 instance on AWS, configured your domain name, and uploaded all the necessary files. However, upon visiting your website, you're greeted with a "404 - Not Found" error message.
Here's a glimpse of what you might see in your web server's logs:
[Err] Request: GET / HTTP/1.1
[Err] Host: example.com
[Err] Status: 404
[Err] Error: Not Found
Analyzing the Problem:
The "Page Not Found" error on AWS can arise from various reasons. Here are some of the most common culprits:
- Incorrect Configuration: The most likely cause is a misconfiguration within your web server's virtual host setup.
- File Permissions: Incorrect file permissions on your WordPress files or directories can prevent the web server from accessing them.
- URL Rewrites: Issues with your
.htaccess
file, which handles URL rewriting, can lead to the "404" error. - Database Connection: Your WordPress website needs to connect to a database to function. A failed database connection will also result in the "404" error.
- Caching Issues: Caching mechanisms like Cloudflare or W3 Total Cache can sometimes interfere with the proper loading of your website.
- Plugin Conflicts: A rogue plugin might be causing the "404" error, especially if it interferes with URL rewriting.
- Theme Issues: Sometimes, an outdated or incompatible theme can contribute to the "404" error.
