Created attachment 8650706 [details] Screen Shot 2015-08-20 at 14.38.03.png Tabzilla is covered by a grey square on readthedocs. Maybe a z-index problem. May be a theme propagation problem.
:shobson surmises that we need to update the RTD templates with new tabzilla code.
We should wait on this until all of our static assets move (again) with django-pipeline.
The work to move static files over (bug 1197444) is just about done. The only remaining task is to remove the /media/fonts symlink, but that shouldn't affect anything here. I think it would be safe to work on this now.
