Facebook pixel purchase event triggered as page view event

[Gokzee]

Hi,

We regularly do ads in facebook. Recently after a server migration, website purchase info is not coming back to facebook. 

Ideally there is a purchase event that is triggered in the order confirmation page and details are sent to facebook as conversion for the ad.

Now the issue is this purchase event is triggered as page view event and not purchase event in order confirmation page.

After several attempts to rectify, we edited the host file and pointed the website (falconfresh.com) to our previous server which was there before migrating to new server.

In that server, purchase event is triggered correctly in the order confirmation page and facebook is recording the conversion.

what could be blocking this event from triggering in the new server. It is triggering as a page view and not purchase event in new server.

any ideas or suggestions

Thanks,
Gokul
