I've built two pages with forms linked to datasets in the site collection. Both work fine in preview - database updated in the sandbox - but throw the error message from the live version and does not update anything.
In preview there are no error messages in the Developer Console. Is it possible that these forms don't work unless a user is physically signed into the site? Right now I only have a generic (PW only) entry point to a members' page which contains links to the two form pages.
I've not seen any documentation which says this is required - I've followed the instructions in the resource page to the letter and am running out of ideas as to why this isn't working properly.
