When I run “normal” Matomo and Tag Manager an one Site, we have some errors in the tag manager:
- The first tag is not getting to the matomo server (Not at all)
- when some other tags are hit the error message “Error: A siteId must be given to add a new tracker” appears
- in the preview-mode everything works fine
- When I only run the Tag Manager it works fine too.
What can be wrong?
