Hi Matt,
Yes, I read it, but I didn’t take any action. As I said, everything else is working perfectly, including all other plugins on the website. I have decided not to use Matomo as I do not have the time to debug this plugin.
If it helps any, I am using a self-managed Gridpane server. Perhaps there is a security feature blocking Matomo; I cannot be sure, but if there were a PHP issue, I would assume the PHP-based website would have more issues than just this.
Thank you for checking back – it is appreciated.
John
