[Plugin: Front-end Editor] narm theme problems

i installed a theme called narm – https://themeforest.net/item/narm-super-flexible-business-corporate-template/127510
i want to use it with the awesome front-end-editing tool from scribu but it just shows nothing whenever the plugin is activated. i deactivated all other plugins but it’s still not working together.

what might help to solve the problem?

best regards
