MarketingCampaignsReporting: "There is no data for this report."

Hi folks!

We are using Matomo On-Premises to track a Web Application and a WordPress Website and we are using UTM parameters for Campaigns. But the Marketing Campaign Reporting Plugin does not work, the page only shows “There is no data for this report.” for Medium, Source, Content, Group, IDs and Placements.

The config.ini.php looks fine with the config of the parameters.

My current thought is, that the enabled cross domain linking removes the parameters before tracking the visit. But I am not able to debug this.

Do you have any idea where I could look?

Thanks! Toby
