Question Insufficient Storage - HTC ONE running Venon 5.0

I have very little installed and yet I am, getting the "Insufficient Storage" to install any apps. When I installed the ROM I moved all my old music, pics and videos over but I am still showing 20.80 GIG of storage available.

Also, my Agenda Widget is not picking up my calender. Dont know if they are related or not.

Help !!!!
