"No element processed for Report Generation" : issue with Knowledge Report

Hello,

I have this issue when I try to launch a Knowledge Report ; 

  1. I click on the Knowledge Report button

I search for a report and select it ; this error message appears : 

"No element processed for Report Generation."

When I try for force the report generation after this first error, I have this second error : 

"Selected XML files does not match the standard xml file for Report Template. Select the appropriate xml file."

 

The thing is that I am the only one to have this error, my colleagues on different computers are able to launch the same report, on the same data without any issue.

Does anyone know how to solve this?

Thank you,
