GitLab

Created by: mrohnstock

Just updated from gitlab 3.1 to 4.0 and migrated from sqlite3 to mysql (as it is required now).

Followed the steps to migrate from sqlite3 to mysql and to upgrade from 3.1 to 4.0, everything went well.

bundle exec rake gitlab:check RAILS_ENV=production got executed without errors.

Gitlab works without errors, but on trying to view /help/markdown I recieve 500-error-message and in /log/productions.log the following appear:

Processing by HelpController#markdown as HTML

Viewing Codeblocks i.e. in issues returns 500, too, and the following appear in /log/productions.log:
