My app worked fine on my localhost and on Heroku until I tried changing the name of my project on Heroku through their website, not the CLI. Now, the app still works on my localhost but I get an Application Error and the message, An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.
Additionally, I was running Ruby Rails 3.2 and updated to 4.0 in the middle of my project to stay as up to date as possible but it's made the whole process much more complicated.
I just started coding and had this project almost finished - just needed to get it synced up with a host and my custom domain and it all went to crap :/ Any help would be very appreciated.
Here is what I get when I run Heroku logs --tail:
