We are running Confluence 7.2.1 following the recommended setup for running behind an NGINX proxy.

We have upgraded from 6.x.

We are unable to edit any of our existing articles and the page is throwing errors in the console in Chrome. The errors are:

(editing existing article)

I don't think it is the proxy but an issue with the upgrade and the plugins.  I would suggest reseting all plugins back to its default state (How to Manually Reset All Plugin Back to its Default State Through the Database) and by cleaning the plugin cache (How to clear Confluence plugins cache).

If this does not work then you should check all of your proxy settings to ensure that everything it setup correctly.  You should specifically look at the server.xml
