We need to edit the page approval form which is coming from my page approval workflow. We have opened our project in SharePoint Designer so we can see the two .xsn files which is inheriting in our workflow and using Infopath 2013 we will be able to edit that file,but before publishing it we need to save it into some location and on publish button click we are getting this error. "An Unknown error has occured. The form template has been published to server,but it can only be opened in Infopath Filler" We are stuck on this error Any Help will be appreciated thanks in advance !!
