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

All other functions of my administration area appear to be in perfect working order.<\/p>\n

My WordPress installation is up-to-date (4.9.8\u2013en_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.<\/p>\n

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

define( 'WP_MEMORY_LIMIT', '256M' );\ndefine( 'WP_MAX_MEMORY_LIMIT', '512M' );<\/code><\/pre>\n
– 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).
\n– Inspecting the memory usage<\/a>.
\n– sudo shutdown -r now (after config changes)<\/p>\n
This issue has me stumped. Any further suggestions would be greatly appreciated.<\/p>\n","protected":false},"template":"","class_list":["post-10940799","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/10940799","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/10940799\/revisions"}],"predecessor-version":[{"id":10940842,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/10940799\/revisions\/10940842"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=10940799"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
