I set up a Piwik server at an IP and have been using it with my Wordpress sites. I decided to convert some of my WordPress sites to HTTPS. Now I am running into issues with insecure content on my WP sites. Looking at the GTMetrix reports for the HTTPS WP sites, I can see that Get Piwik.js from my server, IP listed in GTMetrix, is aborted.
Is the solution to all this to convert my server installation, http://xxx.xxx.xxx.xxx/piwik/index.php, to https? If so, is that possible just using an IP or do I have to convert to a domain name? 2nd, I’ve looked at the FAQ, and I see how to force Piwik to work over HTTP using the config file, but I don’t find anything about how to install an SSL certificate so it works with Piwik. Where can I find instructions on the process?
