My battery percentage and avatar icon tweaks stopped working all of a sudden. I changed a theme and since then I cannot get either tweak to work. It' keeps giving me error messages. I have uninstalled the theme I changed to where it was first lost, and went back to the theme I've been using. Still giving me the error messages. I uninstalled QI and reinstalled 2.7.2. Still errors on THOSE TWO TWEAKS ONLY!

HELP!!
