Have a site with respective DEV and QA environment.
Issue is only with QA, as utag loader(utag.js) file is coming on the page but not utag2.js(s_code for sitecatalyst)
So what could be the possible reason for this to happen, as following are the things had already been checked
- tags configuration section
- tealium code is their inside the head section as top most script
- no load rules are defined
The things to check is that the tag has publish rights to QA. This is under the Advanced settings of the tag.
The other item to check is the versions tab to see what version you currently have deployed in the QA environment.
Anything more and we would require additional details.
