Clicking on issue ellipsis link just shows a lightbulb, why?

Question

Clicking on the ellipsis link next to the issue, e.g.

I get a little light-bulb icon with an x

in the lower right hand side of my window. If I click on a link for duplicated code I get a similar x icon. Why is this? How do I fix this?

Answer 1

This turned out to be a browser problem. I refreshed Firefox and the lightbulb icon now expands to a window showing the correct information. Refreshing Firefox also fixed a persistent "Still Working..." problem where no menus, etc. were available after I installed SonarQube on a new server.
