I am using matomo as a Wordpress Plugin (Version 5.2.0) for some years now on a daily base for my tiny website. It worked fine until yesterday.
The matomo page opens and shows a red box stating that an error happened. In the Wordpress debug log the the error reads:
Uncaught exception: Unable to authenticate with the provided token. It is either invalid or expired. /www/htdocs/w0178452/no-stop.de/wp-content/plugins/matomo/app/plugins/Login/Login.php:132.
As far as I recognized there was only one plugin update of W3 Total Cache stating that it has automatically disabled object caching.
Anything I can do without involving a WP agengy?
Thanks Andreas
