Processing by Admin::LogsController#show as HTMLI have no idea how to fix this or where it comes from. It might be important to note that I installed GitLab on Ubuntu 15.05 wily from the Ubuntu 14.04 trusty package source. There were no problems however! And apart from the issue mentioned above, GitLab seems to run smooth.
I don't think its important, but just for completeness: I messed up a previous GitLab installation
trying to restore a backup from a different version (yes, I know that is not officially supported, that's
probably why things were messed up afterwads). But I ran gitlab-rake gitlab:setup which should've
created a fresh installation of GitLab (it even prompted me that all previous data will be lost).
