Hestia About Section turned black

During testing the About section’s background color on the main page was white and the text was black. Now all of a sudden it turned black. I have installed one plugin but then deactivated it to see if that was the problem and it didn’t work. I’ve also been reloading with cache disabled in Network under chrome. Also added under Additional CSS .hestia-about background color for white and still nothing.

Is there a way to change the background color back to white?

Thanks
