Seems like an error on FB's end, but maybe there could be some improved exception handling in Ultimate FB plugin to prevent this from crashing post-new.php. Issue is that for some reason http://connect.facebook.net/en_US/all.js?ver=3.3.1 is now failing to load on admin pages. In the New Post page, this cascades and breaks other JS on the page and things like the auto post title > post URL and clicking the Add Media button simply don't work any more. This affects every site on our multisite installation. Has anyone else reported something similar / anyone else seeing this?
Any other option but to disable the UFB altogether for now? It's network activated and I know a lot of different sites in our network depend on different pieces. But currently none of our clients can really create new posts.
