Gutenberg

I thought there might be a separate forum for Gutenberg, but sadly if there is I can’t see it, so if I’m in the wrong place, then please advise or move etc

Anyway, I switched to Gutenberg, and the good news is that the front end looks to unaffected, the back end however is a mess. The text has disappeared although there appears to be a lot of white space where the HTML should be. Now I’m using a white font on a black background, could that be causing it? If I try and highlight the white space however, nothing is showing up. I did note however that the black fonts in the title, and different colour fonts on links or specific text is showing up

I was actually hoping that the blocks might enable me to eventually move to black font on a white background without having to alter CSS rules which are probably beyond me, but I was equally hoping that the text would be there! T
