Custom CMS previews work locally but not online

[kylesloper]

For anyone looking for a possible solution:

Styling not applied to preview panel

Testing locally the CMS helped me, thanks again ! I figured it out, it was caused be my locale registering, which need to be in another script block to avoid breaking the style. Weird! <script>CMS.registerPreviewStyle('https://my-blog.com/css/my-blog.css');</script> <script>import { fr } from 'netlify-cms-locales';CMS.registerLocale('fr', fr);</script>
