Hello there,
I have reactivated the plugin and in the backend this Notice is displayed:
Notice: Undefined index: port in /www/htdocs/xxxxxxxx/wp-content/plugins/eu-cookie-law/defaults.php on line 50
In the frontend when I call other pages and blog posts, the error message is gone. But immediately after activating the plugin still an error as described above was displayed. Whether it really has to do with my WordPress Theme Fashionstas ?!
