Bug: Global charts incompatible with PHP 8?

[eteubert]

Expected behavior

„Globale Statistiken für die letzten 30 Tage“ on analytics page works

Actual behavior

Chart shows “Loading Chart failed :(” and PHP error log:

PHP Fatal error: Cannot make non static method League\Csv\Modifier\StreamFilter::validateString() static in class League\Csv\AbstractCsv in [...]wp-content/plugins/podlove-podcasting-plugin-for-wordpress/vendor/league/csv/src/AbstractCsv.php on line 169

1 HINWEIS (no dealbreaker, but should be fixed if possible): 
- The PHP setting "open_basedir" is not empty. This is incompatible with curl, a library required by Podlove Publisher. We have a workaround in place but it is preferred to fix the issue. Please ask your hoster to unset "open_basedir".
