Solution: I contacted Bluehost customer service, and 15 minutes later did I receive the following reply:
"Thank you for contacting support! I was able to see the issue you were having, and I believe I have been able to resolve it. There is a file on the .htaccess that directs the server to where the website files are located. There were two lines (likely left over from moving the site away from the temporary url) that needed to be updated. From what I can see, your site loads great now, please let us know if you still have issues. Have a fantastic day!"
The site is now running normally :)
