@David and @Angus recently created this post that helped solve an issue we had exporting my site’s admin-created theme. After updating, we have another substantial problem, now no one can access posts or PMs at https://forum.ackerlygreen.com. You can see the number of posts, but you’re automatically taken to the bottom of the page and can’t read anything. I attempted to rebuild the forum but received this error: [30%20AM] I can’t see any differences in the admin panel, and I can’t do the few things I know to get the site upright because of these errors. Any help would be greatly appreciated.

Yes, just add https: to the beginning

Have you specified DISCOURSE_CDN_URL in your app.yml file? If so, make sure it has a protocol at the beginning (e.g. https://)

The visible error on your forum is caused by the retort plugin. Once you manage to successfully rebuild, it should be fixed [image] Discourse Retort Plugin I’ve just pushed a fix which removes _.contains from the repo, so this should start working again.

Thank you @David. Much appreciated.

Thanks so much, the forum’s up and running again.

@david, I’m so out of my depth here, but this is what the CDN url looks like in my app.yml:

Should it be an absolute url as mentioned in your above response?
