Can't add a step: "parsererror Syntax error: JSON.parse: unexpected end of data."


     When I try to "add a step" to an Instructable, I get the following error message: 

          Syntax error:  JSON.parse:  unexpected end of data

     (I've included a screen capture below.)

     I'm trying to add steps to the following Instructable:  behold

     I'm using a Windows PC (Windows 7) and Firefox 25.0. 

     Is there something I can do to remedy this?

Many thanks for any assistance you can provide!
