The background of my blog site is black, and until three days ago the text was white. Suddenly the text is black so that it is invisible. I then changed the text to white, which is visible, but not to all of the subscribers to my blog. They receive my blog with a white background, and now that I've changed the text to white, they do not see any text. I do not understand why my text suddenly turned black when I did nothing different.
The blog I need help with is naturallycuriouswithmaryholland.wordpress.com.
