Customizr control planel creates internal error

I upgraded to WordPress 4.1 and upgraded to Customizr 3.2.10. The website works but I can’t Customizr template the control panel. When I try to enter the Customizr control(template control panel) the one that appears on the left, my system says internal error.

I can get into my Dashboard but not my Customizr template setting – I keep receiving (Internal Error), this has only happened since the update to WordPress 4.1 and Customizr 3.2.10 a few days ago.
