Dear Mario,
It can be your theme or another 3rd party plugin conflicting issues. In this case, try to use another theme and deactivate the 3rd party plugins to check the issue. Because our plugin has no issue like those. You can check out our plugin live demo as a reference.
Moreover, you could use the FoodBook Theme that we have provided for FREE with the FoodBook.
Best Regards,
ThemeLooks Support Team
