Java error on the "share" tab of published instructables

When I go to the Share tab of my published Instructable I get the following Error:
Please excuse me, that was very impolite! - javax.servlet.ServletException: javax.servlet.jsp.JspException: ServletException in '/common/layout_editor.jspx': ServletException in '/pages/edit/share_body.jsp': Arguments to 'pdfURL' do not match expected length 2.

Just trying to get the code to embed the instructable on my website.
