Hey @tom.woodley, thanks for posting and using Zoom! Can you try just running `$ http-server` in terminal instead of `$ npm run start`? Thanks, Tommy ---

Hey @tom.woodley, Did you try running `http-server` in terminal? Thanks, Tommy ---

I think so… Sorry if I’m missing something obvious here. So, I run http-server from my terminal and get this ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/3/3fcf69cf6da62caf32e352aaece817d85b004642.png) I’ve checked my package.json file and http-server is listed as a dependency. To double check it’s installed I’ve run `npm http-server -v` and get 6.4.1. Is that what you meant? ---
