Redmine-GitLab integration described here somehow doesn't work for me this way. I can't refer to an issue using #<ID>
or <PROJECT>-<ID>
- it becomes just plain text.
To get #<ID>
working as a link to Redmine issue:
In GitLab go to "Settings->General->Visibility, project features, permissions" and disable "Issues". Redmine integration in GitLab has to be enabled, of course.
Now it should work as expected: the "plain text" becomes a link.
