This blog: http://stsmpt.nwsltr.info accepted three posts by email a few days ago. Today, post by email is no longer working. Each time, I receive an email back from WordPress.com with this text "Please note that some attachments were rejected for the following reasons:
- Shoulder Pain.jpg - Unknown token"
Both the text and the jpg are getting rejected each time. The blog is currently running JetPack 2.2.5. Can someone please elaborate on what the problem might be or point me to a resource?
