Mautic not recording page hits any more


I have a Wordpress site which is connected to Mautic via WPMautic plugin. 12 days ago I switched the Wordpress site from HTTP to HTTPS (only Wordpress, not Mautic). Since then no more page hits are recorded and displayed on the dashboard. What work: tracking of email opens, email link clicks and asset downloads.

Any idea what goes wrong? When I open the site’s source code I can see the correct tracking script which is accessible via URL.

Any help is highly appreciated.
