XF 2.3 Can anyone tell me what is causing this error?

This error is specifically related to the Ads Manager 2 by Siropu add-on for XenForo. The function sam_counter is a custom template function that the add-on uses to track and display ad impressions or rotations.

The error "Function sam_counter is unknown" occurs because a XenForo template is trying to call that function, but the underlying PHP code that defines the function isn't active or loaded.
