Theme ‘Customizer’ Preview Grey Despite Untouched WordPress Installation

    My Problem: The theme customizer located at /wp-admin/customizer.php?url=http%3A%2F%2Fexample.com%2F, displays a grey preview with the meta title “Customise: Loading…”

    All other functions of my administration area appear to be in perfect working order.

    My WordPress installation is up-to-date (4.9.8–en_NZ) and hosted on a DigitalOcean VPS “droplet” running on Ubuntu 18.04.1. Earlier today, this website was hosted on Hostinger’s servers – the problem persisted then, too.

    What I’ve tried thus far:
    – Changing browsers, Opera < > Google Chrome.
    – Clearing my browser cache.
    – Totally resetting the browser (including extensions) just in case it missed something.
    – Connecting via a proxy.
    – Switching hosts entirely, Hostinger > DigitalOcean.
    – Deleting all the default plugins.
    – Deleting all the other default themes, except Twenty Seventeen (default).
    – Shaking my fist angrily at the computer monitor.
    – Watching for errors in the browser console whilst loading the page. These Mixed-content SSL errors are shown, but I somewhat doubt are related.
    – Adding the following lines to my wp-config file:

    define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

    – Changing ‘WP_DEBUG’, false, to ‘WP_DEBUG’, true, and then watching for page errors and inspecting the wp-content directory for a log file (nothing).
    – Inspecting the memory usage.
    – sudo shutdown -r now (after config changes)

    This issue has me stumped. Any further suggestions would be greatly appreciated.

    RESOLVED!

    For those in a similar situation, I was wrong to dismiss the mixed-content errors. The issue was, in the end, related to my website’s SSL.

    To resolve, I simply had to install a plugin that converted any lingering HTTP links to HTTPS. (The one I installed was called “Really Simple SSL”).

    Cheers.

    Alternatively, you could have run the PHP script SearchReplaceDB2 this script will change the url’s in the DB quickly and easily.
