Traffic from Chrome browsers stopped tracking via the http api


I’m using this great wp-matomo plugin on my network of Wordpress sites, specially the proxy mode that works fine. Since a few days I noticed my traffic was declining inside Matomo (on all sites) and after doign some research I found that it basically stopped counting any Chrome browser traffic. When inspecting my pages inside the Chrome console, I noticed this error

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Again, this is only in Chrome, other browsers are not giving this error in the console and traffic is tracked fine.

Matomo was updated 2 days ago and these things started for me, so I suspect it’s Matomo? When using the tracker without the proxy, it’s working fine but I suspect a bug in the http API of Matomo? or do I need to contact the wp-matomo plugin developers?



Can you check in the Matomo error log file?
