If the loaded css from the s2.wp.com domain is necessary for the plugin then the solution will come from the programmers of the Jetpack plugin, is his server.
Hi everyone!
I’ve the same problem, when we try to publish a post the plugin returns the following error:
While publishing “the_post_name_blabla” to Facebook, an error occured:
Facebook returned an unexpected error: An unknown error has occurred.
Try to resolve this issue, update the plugin or inform the author about the problem.
[Error occured at line 347]
It’s very weird, the plugin and the Facebook app still works pretty fine with other two facebook pages, but with not with this one.
Any Ideas?
