I have purchased the matomo heatmap and have some trouble getting started. I have added the site to Cross-Origin Resource Sharing (CORS) domains, and have checked this in the config.ini. On my site I still get the error:
Access to XMLHttpRequest at ‘x/matomo.php’ from origin ‘x’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
I am out of ideas
Please help me. I am able to acces the nginx server to edit there but i do not know what to add and where. And should I add the Access-Control-Allow-Origin on the matomo on premise website or the website that needs the tracking?
Thanks in advance
