Most of my Google searches returned issues where people couldn’t view their repositories, but I could see mine fine…

Then I looked at the error messages again and noticed it was looking for a repository called favicon.ico. A quick Google later and I found this page:

Adding the suggested items to my Apache conf fixed the problem!
