I am generating a Public portal using Sharepoint 2016 on premise where I am using CQWP in my web page with my custom style sheet to get the desired columns from lists.
Issue is : Authenticated users can view the Data in CQWP data. but it is not showing any data when accessing by public/external users.
it is showing the following message: "Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator."
Correlation ID: XXXXXXXXXXXXXXXX
I got a solution where it is said that by exporting the CQWP and add value
in CommonViewFields Property. But it didn't resolved my issue.
