Possible fixes

We're tired of 404/500 errors in gitlab. This is not serious. We moved here to do less devops, not the exact opposite. Can you focus on one thing and do it right please ? It's frustrating and we're starting to regret not going with github instead of paying for gitlab.com.

Please fix this 500 error as soon as possible.
