Facebook page blank

I have been looking all around for the same problem, suddenly my Facebook account started to log in to a greyed out blank page, other FB accounts i manage load fine but not mine. Scrip loads in developper mode, but nothing in the browser... (Yes i went through the classic stuff; emptied caches, history, cookies, disabled extensions and plugins, i even downloaded an old saved Safari browser from TM and it did the same...) My page works fine in Chrome and on my iPhone's Safari, everything else works fin in my iMac's Safari 🤨

(Edit: When in Develop mode, if i switch User Agent the page appears but full width like an oversised iPhone, if i switch back to default User Agent it blanks out again)

Have you also tried accessing the page with a different browser? If both get the same result, that would indicate the problem is with Facebook.
