I’ve put in place this set of changes, helpfully recommended by AdamS in the ICP Developer Community Discord:

> You’ve set up your URLs wrong.  
> The assets dir is not a component of your URLs. assets contains static data, and is served from the root, same as generated data does not have `dist` in the URL.  
> And then you’ve set a script to be imported from `/src` , which isn’t included in the assets container at all, and which is superfluous; the bundler converts your JS code to a single file that’s already being loaded in `<head>` for you.  
> Delete the `<script>` tag from the `<body>` , and change the `<link>` tag to point to `/main.css` .

The CSS and embedded image now display correctly but still nothing is functioning. I also tried removing all references to the internet\_identity canister since this is not needed in the IC version, and deleted and re-deployed the full set of canisters. It now just gives this one error:

This frontend (one of two) is now deployed at [https://qb7ig-qiaaa-aaaao-a2h3a-cai.icp0.io/](https://qb7ig-qiaaa-aaaao-a2h3a-cai.icp0.io/).
