Facebook Pixel stopped working

Hi!
Our Facebook pixel stopped working on May 18th...no data is coming in/tracking. I believe this was the date that we were upgraded to version 5.4? Can you please help look into why it stopped working with the new software version?

Secondly, prior to May 18th we've noticed a huge discrepancy in the revenue from what the Pixel is reporting vs. the monthly revenue that our AllProWebTools console is reporting?

We will be happy to look into this for you, please provide administrative access to your Facebook account.

Ok sure...what AllProWebTools account should we give access to?

From what we've looked into it's not an issue in the actual Facebook account but rather that the code is not inserted on our website properly or on the correct website pages. Here's the screenshot of where the data just stops tracking.....where in the console can we check that the code is added to our website's persistent header?

any update on this?

Could you please provide support with helping resolve this? Ever since our 5.4 upgrade on May 18th our Pixel is not tracking any revenue at all and our Facebook Ads have no purchase pixel it's completely gone. We would greatly appreciate your help to correct this seeing as we are going on almost a month with no revenue or purchase data from our Pixel....please could you respond to us.
