[Google Analytics Problem] Conversions stop work

[Ser_J]

Hi, 

I changed checkout steps in my E-commerce from normal checkout to one-page checkout. 

Since I made this change, in Google Analytics I can't find E-commerce conversions (when users make an order).

I see that the order page has changed from /order to /fast-order, but the thank-you page is the same, so, I guess, nothing has changed for Google Analytics.

What do you advice me?

P.S. = I made also some fixes to tpl files, but I didn't touch Header, where the Google Analytics is installed

P.P.S = I use GAnalytics module and I tried to reinstall it, but the problem is the same
