Hi,
I got this error on my Facebook business manager while using this plugin.
ISSUE
Your server is sending an invalid ip_address, user_agent parameters value for your AddToCart event. This may be because there was an error in the parameter value.
This may cause issues with the attribution and delivery optimization of ad campaigns that are using this event.
SOLUTION
Check that you’re sending valid and unique values for the ip_address, user_agent parameters for your AddToCart event and that the data is normalized correctly.
What do I do?
