Its ok, I worked it out.

It worked with do_widget id=tumblr-widget-2 but not do_widget “tumblr-widget-2”

Which appear from the docs to be equivalent

OK, so options are, either put a wordfence clear cache into wp-cron (e.g hourly)? Could you give example code for this?

Or create a commentable post / page which is “scheduled Cache Clearing” and Cron a comment onto the page every hour.

Would it not also be possible to embed php code: wfCache::scheduleCacheClear into a page template somewhere, and just open a page with that template? Seems like that function bypasses the admin checks.
