I am trying to prepare a zip file to import new articles into my org/sandbox but having trouble with mapping some key rich text area fields such as solution__c and Description__c. When I add them to the csv file that I am using in the zip file. I get the following error: "This value [Description] in the header for column 6 cannot be mapped (check both the header and its matching FLS). [MESSAGE 4/16/2013 8:34 PM] -- Import Failed --" I get the same error for both fields and some other standard fields such as publishstatus. I checked the field level security including all the required knowledge permissions and everything looks fine to me. Does anyone know what I am doing wrong?
