I just updated my joomla site on my dev machine to 3.6.4 and I'm having a problem with the module manager. I can access the module manager just fine, but when I try to edit a module I get sent to a white page with a drop down list of modules but not other info. enter image description here. I'm relatively new to joomla, so I've never experienced anything like this before. Any ideas what this is or how I can diagnose it? where would I stick php error reporting to get more information about why this is failing?

Update: I also get this problem when trying to access modules through the module assignment tab via menus...

If anyone else runs into this, clear your browser and joomla cache. The javascript handling the module manager UI was changed and conflicts with what is stored.
