Once a word press theme is uploaded to server, what plugin do I use to edit the content? Example: All I want to do is change a word or two on the home page so I go to Login to word press>Pages>All Pages> Home>Edit, there is nothing there. Go to code editor all that is there is CSS call outs. However when site is visited all the content is there. So do I need a plugin like block editor, Gutenberg, or what? Basically one I hand a site off to a client how do they make changes?
