Jira boards and menu bar entries are empty
After updating a bunch of plugins, our Jira 8.5.2 stopped showing the default login screen (sitename.com/secure/Dashboard.jspa) and the menu entries in Dashboards, Projects, Issues, etc. are empty. The custom menus like Tempo or Projectrak are working fine.
After looking into the logs, I haven't found anything relevant to plugins. The web console giving me 3 errors during the loading of the front page:
After clicking on any other menu entry in Tempo or Projectrak, all the menus and boards are working well.
Do you know how to fix this issue?
