Sorry, I can’t find where to change the home page main image at the top. is that a hook or other element (pink large image with woman on top.)
Also, where can i change the title of green button?
go to Apperance > Elements and you will see a header element assigned to the Front Page.
Edit that to change the content, button link etc. The background image is the featured image of the page – so edit the home page and change the featured image.
