Because of this error I’ve heard that we have to deactivate Pagespeed to use Piwik.
Unfortunately the method which is described in the FAQ (How do I configure my server to let Piwik serve HTML files? - Analytics Platform - Matomo - url tag does not work here) doesn’t work:
pagespeed Disallow "*/piwik/*";
We’re using nginx with Plesk 12 and Piwik is installed in a directory on the main domain. So we’re not using a subdomain for Piwik Is this possibly the reason that it does not work?
