I just installed the plugin and it seems to be working well except for the Pinterest content button. The form appears and properly submits the post and image to Pinterest, but it only works about 1 out of 10 times. The rest of the time I either get a 502 error from Pinterest ("Oops our server is experiencing a mild case of the hiccups) or it just returns the popup form again (except blank).
Any thoughts or suggestions? Thanks!
