Seems Safari’s cache is corrupted on my Mac, several of the WordPress admin pages look like this:

Corrupted Safari cache when viewing WordPress Admin page.

To get around this issue, I’m temporarily using Microsoft Edge, which seems to work fine.

I tried erasing Safari’s cache for my schwie.com domain and then quit/restarted Safari:

Go to Safari > Settings > Privacy and click Manage Website Data.
– In the search bar, type the name of your website.
– Select it and click Remove.
Restart Safari and check the WordPress admin panel
– Close and reopen Safari to ensure the changes take effect.
– Revisit your WordPress admin panel to see if the changes are now reflected.

But the above instructions didn’t seem to resolve the issue in Safari. More aggressive action with Safari may be necessary, but I’m reluctant to try it now.
