I was recently developing a site and the copyright section vanished on me.
I’m running the latest version of all softwares, I’ve since disabled all plugins besides GeneratePress premium and removed the custom CSS in Customizer. No effect anywhere.
I’m not sure exactly when it disappeared, but I believe it was while working in Safari’s ‘inspect element’ system. Loading the site in Chrome and in cache-free private browsing pages did not restore the element.
Apologies for the confusion – that is a widget area, which is displaying properly. The copyright section in this design is supposed to be on the left-hand side of the screen and is not visible in your screenshot.
