You need to open the customzer from the page. Go to Pages, click on your page, when opened click on Codeless Builder (screenshot). This way you can have access on page’s elements and edit them.
I already imported the dummy data using another way(without images as it would increase the dummy data size). To change in the future the header or footer, just go to Codeless > Home and click on “Import Header”/”Import Footer”. Click on the desired header/footer to start the import and in seconds you will have the new version installed.
Sometimes the images of the slider are the ones not showing and this makes it look as the slider is not there. Can you please add some wo credentials in a private reply? So we can check.
