Unsupported Class issues - 1

[shreyasgoswami]

What did you expect to happen?

FB analytics code to work seamlessly along with Google Analytics Tracking code

What happened instead?

Following error comes up in IA production feed when I add FB analytics code along with Google Analytics code

“Unsupported Class: The

element has an unsupported class value in the class=op- tag. For more information on the class values supported in element you’re using, refer to the Format Reference of the Instant Articles documentation.”

For Google, I just specified the Google Tracking ID in the provided box.
For FB Analytics, I pasted the following tracking code in the “Tracking code” box

<script> window.fbAsyncInit = function() { FB.init({ appId : ‘xxxxxxxxxx’, cookie : true, xfbml : true, version : ‘v2.8’ }); FB.AppEvents.logPageView(); }; (function(d, s, id){ var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) {return;} js = d.createElement(s); js.id = id; js.src = “//connect.facebook.net/en_US/sdk.js”; fjs.parentNode.insertBefore(js, fjs); }(document, ‘script’, ‘facebook-jssdk’)); </script>

I have replaced my Page ID with “xxxxxxxxxx”.

How can we reproduce this behavior?

Just follow the steps mentioned above

Can you provide a link to a page which shows this issue?

Technical info

• WordPress version: 4.7.4 (up-to-date)
• allfacebook Instant Articles version: 0.9.1 (up-to-date)

Is it that I can place only one of the two tracking codes? Or there is some error in the way I am placing the tracking code for FB?

I am having this same issue. One thing I noticed after going through and editing the markup in Facebook publishing tools is if you remove any extra <iframe> tags so that all scripts are wrapped in a singe tag, the error goes away.

I currently have three tracking scripts that need to run simultaneously, so any help with this would be greatly appreciated.
