If I try to open any filter, the results appear correctly, but the Issue Navigator doesn't completely load. In fact, it only loads the issue list in the middle pane. The right pane (issue view), the left pane (filter list), the top bar (IIRC to edit the JQL) and all popup menus don't load.
I didn't do anything different except create more issues, but there still aren't many (43 total). Also, the maintenance window has passed already, so I don't think that's it.
What can I do to attempt to solve this?
