Dear Mario,
Please let us know the version number of FoodBook that you are using.
If you are using an older version of FoodBook then please download and use the latest updated version of FoodBook to get rid of the issue or it can be an issue of 3rd party plugin conflicts. You can deactivate other 3rd party plugins one by one to check the conflicts. Because our plugin has no issue like this.
Best Regards,
ThemeLooks Support Team
