Hello @wp-opti
The problem with WP-Rocket appears only during the archiving process (This process loads your visits and transform your data into the reports): so you’ll have visits in your visitor log, but no data displayed in your reports.
To fix it, you could downgrade to a WP-Rocket compatible version.
https://github.com/matomo-org/matomo-for-wordpress/wiki/Downgrade-wp-rocket-to-a-version-compatible-with-the-Matomo-plugin
There are no security issues fixed since this version, so it should not be a problem to downgrade to this version.
Our patch is in progress. It should be released in the next Matomo major version, which is the next scheduled release.
Kind regards
Mat
