I’m currently working on a website for one of my client, Frappe Builder is working fabulously!
Although, After publishing the website, its not publishing as shown in the editor. Couldn’t attach video of what I was explaining but attaching some screenshots.
The discrepancy occurs on sites with https enabled, this happens because frappe adds resources with https by default. In the builder app, there is a css reset that is already included in the html, but in this case the browser blocks it because it cannot be accessed securely with https. The reset file in can be found at http://[your-site]/assets/builder/reset.css.
