Suddenly (not after an upgrade) the ‘Customize’ option is broken.<\/p>\n
When clicking on ‘Customize’ only the ‘Widgets’ come up, see screenshot:<\/p>\n

.. and when clicking on ‘Widgets’ to edit settings it is not actually possible ti edit anything, instead only this message appears:<\/p>\n

In the browser tab there is this notification: ‘Customize: Loading…’<\/p>\n
If I go directly to ‘Widgets’ from Appearance in the Menu, I can edit the Widgets section; and I can also edit ‘Menus’ that way.<\/p>\n
….but if I go to ‘Header’ or ‘Background’ directly from ‘Appearance’, then I end up in the same broken ‘Customize’ as shown in the screenshot above.<\/p>\n
Steps taken to repair (NB: PHP is v. 7.4):<\/p>\n
*Re-installed WP 5.4.2
\n*Activated default theme (Twenty Twenty)
\n*Deactivated all plugins
\n*Deleted cache
\n*Tried Chrome (using Firefox normally)<\/p>\n
What else can I try?<\/p>\n
PS: I have sites on same server with same theme and same plugins that work fine.<\/p>\n","protected":false},"template":"","class_list":["post-13071908","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/13071908","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":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/13071908\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=13071908"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
