I need help because my Gitlab issues seem to be down. At first I thought it was a bug of Gitlab itself but I researched and no one has the same problem so I assume it is something with my server. The list is there and I can add new issues, but I cannot close them or edit them.
When I open them they look like this and never load further content:

When I add them, I cannot change type, asignee, milestone... nothing. I can only edit the title and description. And once it's created, it can never be edited again.
I discovered also that they can be closed and reopened from the Boards view, by moving the cards between columns.
Any idea what could be causing this and how can I fix it?
