Hi Val,
Thanks for the assistance! I took a look at the PHP logs and noticed the plugin exceeded our memory limit on our test website. Now that we upped our memory limit the plugin works.
Hey, sorry no we haven’t found a solution yet. Now we are just doing a work around in GTM where the events are just fired once per page. This means we are missing a small number of A2Cs that are done more than once on the same page (e.g. ajax cart a2cs).
