Yes, indeed it is.
Actually you can still see the header "Description" on the left side of the page, but on the right where the text box is...nothing!
Or I should say the text box, with current text inside, appears for just a fraction of a second before going away. The word "Description" remains.
It has worked in the past, but recently with some change it has gone away :(
I am not actually sure what theme I am using. It was based on some free one from a couple years ago, now modified. But I don't see a reference to the theme name (although I might be looking right past it and not even know - the current theme in Appearance > Themes just has the website name on it and then the text below says "custom theme" which I guess was changed by the person who helped me ages ago).
