On all my browsers Firefox, Chrome + Chrome Mobile, Edge and IE the embedded Opt Out iFrame is not working…it´s only white space.
Other iFrames from different sources are working fine.
Piwik Script is getting integrated into my website with Haeder-Footer-Plugin…works fine.
I don´t want to use more Plugins like "WP-Matomo (WP-Piwik) + Matomo web analytics application.
Any solution for that?
