I am sorry but it is not as simple as that.
1. I have a slider on the home page which was added via the “Enable slider” on home page in your previous versions.
2. I understand that you kept the backward compatibility of slider feature so that I can see the slider on the home page.
3. I very much hope that you are keeping the backward compatibility – otherwise my home page will be ruined and I assume you don’t want to riun that for me.
4. I disabled the #featured-content.grid.col-460 section because it is showing your default text “Happiness is warm cup” or some such.
5. When I enable the feature section to add my own text (without any images – I just want to add one sentence), I delete your default text and add my own text in Customizer, my text does not show up – the section is empty.
6. When enable the feaure section without changing your default text, your text “Happiness is warm cup” shows up.
So this is what I mean. It is not as simple as that. Can you please look into it. By the way, I am doing this on my local computer, not on the live site because in my experience anything new in your updates is likely to ruin something, so I have to be very careful.
