I just upgraded via shell on a DigitalOcean installation with any size Discourse forum. All is working fine, with the exception of the plugin area in the Administration panel, which is entirely blank.
If I go to admin/upgrade, the list loads fine, instead.
I see this error in Firebug coming from a js file:
Error: There is no route named adminPlugins.index
Tried to search in the forums for the same issue but I could not find anything.
I attempted multiple rebuilds and disabled plugins, without luck.
