Dear Roberto,
We have identified the issue. It was a translation issue. When you translating a word, for Example: FoodBook Settings menu, it also translates the menu slug that’s why the setting were not working.
We have listed this in our plugin update list to add the information in our next update of the plugin and we will do it ASAP.
Please wait with patience for the next update of the plugin. You will get notified via email when the update will available to download.
Moreover, thanks to cooperate to identify the issue.
Best Regards,
ThemeLooks Support Team
