Mobile theme settings gives a blank screen (dashboard)

Hello,

I am using the WP Mobile Detector plugin version 3.2. Apparently, when I go to the Mobile theme settings page in the dashboard, it gives me a blank screen, not giving me the option to select different themes. I have tried installing the latest version 3.5, it still gives me a blank screen.
I have tried deactivating all the plugins, giving permission 777 to the folder, and still it does not work. I am using the latest wordpress 4.4.2.

Thank you
