The page settings have the title background option. It was transparent on the white background of the page and the content was also white that is why you could not see. I have set the black background for the title and now you can see the categories https://prnt.sc/v3of3v
I wanted to add an image in the background. Can we revert to a white background with the default image that comes when we import the demo? Besides that you will notice something called jewellery next to the home decor which has a small icon.. how do I remove it?
Could you redirect me how I can do the changes in the future?
