I relaised that the generic-release project was unneeded, something went wrong in its deletion. it caused the pagure.io home page to give a 500 error, I added the project back and the front end was fine. but on subsequent deletion it broke the home page again so I added it back. all three generic-release projects that are shown need to be deleted.
I cleaned things up and I might have found what went wrong in the deletion, I'll need to test it some more next week but hopefully it's fixed.
Thanks for the report!
