I'm troubleshooting why my WP-Piwik plugin or Piwik installation, which both have been fine for almost three months, have not been detecting users' visits for the last five days including my tested site visits on a device without admin login. I have Piwik installed on separate server from the WordPress installation.
The plugin's Settings home page reports that:
You are using Piwik 2.1.0 and WP-Piwik 0.9.9.8.
Auto site configuration is enabled.
Tracking code insertion is enabled.
I've tested whether it may be my API by resaving the settings but it didn't help. After doing so, my stats history on the WP-Piwik plugin dashboard and navbar chart have been reset, for some reason. The Piwik installation however continues to show stat history so I believe the issue may lie with the plugin.
As suggested elsewhere on this forum, I've tried deactivating my cache plugin, W3 Total Cache, and reactivating it without a fix.
Does anyone know what else I should do to troubleshoot or fix?
