I think you are referring to this http://wordpress.org/plugins/jotform-integration/ if I am not mistaken?
Have you tried the standard method for adding a form to wordpress instead? Please see http://www.jotform.com/help/4-Adding-Forms-to-Wordpress for further instructions.
Unfortunately though, As far as I know this was actually developed by one of our fellow users " Patrick Rauland " whom has programming knowledge specifically for wordpress usage and not by us. We have mentioned this in our guide here so I'm not sure if we have any plans to change that since the plugin was already made but you can contact the plugin author here. If we are able to figure out a fix then we will let you know though.
