Hi! Thanks for a great plugin, we also just started to using GTM4WP.
I noticed the same error in the console on our page. It seems like some other js functions on our site won’t work properly when the error shows up. But sometimes when I reload the page the error is gone and the other functions work as they should again.
The error is in this file wp-content/plugins/duracelltomi-google-tag-manager/js/gtm4wp-social-tracker.js?ver=1.2
line 63: window.twttr.ready(function ( twttr ) {
Uncaught TypeError: Cannot read property ‘ready’ of undefined
Not sure if the error is caused by a conflict with a previous twitter box or something else.
I solved it for now by unchecking the “Social actions” checkbox under the [event]-tab since we don’t need that functionality.
