After a long struggle to get the pages to load in full HTTPS and have no shield on Chrome (warning of unsafe scripts), I have a few more issues on my site that I can't seem to fix. I hired an nginx expert that made the site's backend very good, and he claims there's nothing wrong with the nginx configuration. I believe him especially because the exact same configuration works fine on other Xenforo sites. I am using the Legendary theme for Xenforo 1.3 by pixelexit.
Any help on this would be greatly appreciated. If you're feeling kind enough to assist me with this, I ask that you please explain anything I should do in a fair amount of detail so that I do not get confused. Thanks!
