So there is currently a bug in utag.js... and i cant work out how to actually update the utag.js code...
This most may be realted so if anyone could help would be appreciated.
I have replied to your post at https://community.tealiumiq.com/t5/Developers/Getting-exception-in-utag-10-js/m-p/11288#M4275
P.S. I don't want to be picky, but want to clarify in case anyone reads this thread in the future. There is currently a bug in the Tealium Template for Google Universal Analytics, not a bug in the utag.js (a.k.a. UTAG Loader).
If you would like a Tealium Solutions Engineer to make the change for you, you can open at ticket at:
