I think I already asked this, but can't find it (over a week ago!), so I've just come back to it. I've worked through the quickstart tutorial for Vue.js (on my Mac) and all OK (after getting over the package.json license error. So the last two commands are yarn install and yarn start & I get the program running, but when I add a new post and enter some info, it does not save - nothing happens, it just returns to the popup entry dialog - any thoughts ? TIA, Dave
