I have a website which I've built that I have gone to a bunch of times today. Out of nowhere I receive a 404 Page Not Found error, I didn't do anything.
The site loads an index.html file which points to a main.php file which loads the content. Those 2 files are in the same directory and intact. I have no idea why this is happening - how can I troubleshoot the problem?
I have already: cleared the cache, tried a new browser, triple-checked the file paths, and checked my hosts file.
