I've just installed the Publisher theme on my Wordpress and the settings are not working. And these errors are in the console

Uncaught ReferenceError: Fuse is not defined
    s blog/wp-content/themes/publisher/includes/libs/better-framework/assets/js/selector-modal.min.js?ver=3.10.15:18
    bs_selector_modal blog/wp-content/themes/publisher/includes/libs/better-framework/assets/js/selector-modal.min.js?ver=3.10.15:18
    setup_select_popup_field blog/wp-content/themes/publisher/includes/libs/better-framework/assets/js/admin-scripts.js?ver=3.10.15:900
    jQuery 2

I can't find such thing as Fuse in the code. Is my theme missing some file or is it a version conflict between my wordpress and theme.

The php version is 5.6 because I have prestashop in the same address beside wordpress and it has to be 5.6. The wordpress itself is 5.5.6 and the theme is Publisher 7.6.2
