Facebook won't load on safari since 11.3 update

When I go to Facebook website, nothing happens, blank screen. I've checked in 'settings for this website' and enabled all, no content blockers etc, and deleted all cookies, cache etc from browser so when I go to Facebook the next time it asks me to accept the cookies and login, which I do, then still blank screen. Works fine on chrome and Firefox and worked fine until 11.3 update so clearly a safari issue? I get a loading bar in URL window briefly but then nothing. Disabled all extensions too. Anyone help?
