insufficient internal memory

My htc desire 816 has been recently been giving me an insufficient internal memory error every time i try to install and app weather it be from the play store or from an apk. I have over 2 Gb of free space and uninstalling apps doesn't help. Wiping the cache and dalvik cache does nothing as well. I am running on an unoffical build of cynogenmod 11 (kitkat) and have root.

Any help would be greatly appreciated.
