Nginx, Wordpress, admin modal windows blank. Stumped.
Last evening I installed Wordpress on a fresh, SSL, LEMP stack. I’ve done this several times now, following do’s excellent tutorials.
Everything runs great, except on every install, the modal windows used in a few places within Wordpress admin side always open blank.
The easiest place to see this is when clicking the “plugin details” link on any plugin in the plugin list. Likewise, if trying to use the Customizer, the “live” view of the website is blank.
Both are basically trying to pull data from external links into a modal window.
Is there some nginx config adjustment necessary, or firewall perhaps, to facilitate this??
