Hi there, even though it’s configured correctly in the original site, you’ll still need to set up the theme options and settings inside the new theme to replicate manually, unfortunately these aren’t automatically populated.
So in the new site you’ll need to make sure the slides are set up in the slides panel and the images are loaded. Then go to appearance>theme settings>slider and make sure they’re setup to show on the home page and the relevant times/transitions are set etc.
For the menu card, go to edit the menu card page and scroll down to the “page categories for menu card” section and make sure the relevant categories are checked to display as per the original.
If you’re still having problems, please email a login to the new site via the contact form at http://www.redfactory.nl/contact-us/ with a link to this forum thread and mark for my attention.
