I am using both SFC and STC for the record.
I posted in another thread but got no reply, so I'll make my own.
I have all three of my tokens, the text is with a green background. I had one post work. Then I uninstalled because I disliked the shortlinks the plugin used. Then, I reinstalled, and saved my setting (that were already there... bad plugin deletion cleanup, dev) and tried to post again and it didn't work. I the found out that I lost my tokens, two of the, the top and bottom of the 3 in the list. So, I had to sign back into the FB account and re-auth, which was successful. Still cannot post automatically to facebook (or manually).....
