Tag Manager Debug Mode | error

Hi!

We have a problem with our Matomo Tag Manager debug mode. We’re managing 4 websites, but for one, the debug mode isn’t working properly. It is showing (in some strange way), but without any workable layout.

Is this a problem that other people encounter as well? We can’t find the issue when comparing websites.

The one site probably blocks CSS or Matomo tag manager is not white listed in CSP.
