Fatal error with Wordpress WP-Matomo Integration plugin

Hi everyone, I had a fatal error using the WP-Matomo Integration plugin:

Fatal error: Access level to Piwik\Plugins\Actions\Columns\ActionUrl::configureSegments() must be public (as in class Piwik\Columns\Dimension) in /piwik/plugins/Actions/Columns/ActionUrl.php on line 29

I contacted the plugin developer and he said:

“This looks like an error in Matomo/Piwik and not in this WordPress plugin (WP-Matomo/WP-Piwik). You should post this in the Matomo forums.”

Cannot access data, any suggestions. Thanks Juli
