Hey there forum members! I’m having issues connecting a nextjs site to [builder.io](http://builder.io)  
I used the github repo “builder\examples\next-js-builder-site”, changed the API key in the .env files and the site url in the [builder.io](http://builder.io) site, even installed the extension and allowed unsafe content, I’m honestly lost…

Hi @Doggo,

To clarify, is your site’s preview not loading? Can you share your organization’s public API key (you can find this in your organization settings) as well as a code reproduction?
