Monday at 12pm something changed, OCP v4 is now posing as a visitor instead of to the timeline as the page.

I have forced a password reset in Facebook and confirmed this in OCP so it's not a password issue.  All the OCP settings look to be correct, page ID etc.  Twitter posting is working as expected.  A similar thing happened once before and it was an update of the Facebook API,  Is anyone having this same issue?

If you look at our Facebook page the posts should display on the timeline as (Hospital Radio Yare - psquared posted) not myself in the visitors posts to the right of the page.  www.hospitalradioyare.com

Any ideas?  This happened Monday at 12pm and no settings has been changed.......
