This might be a quick answer so here is the question.

I installed Better Together add-on on my test store. No problem. Just simple copying the files in the right place and it works fine. (I even translated all the working files for my bilingual store) Now, i do it on my actual store, going through the same copying and it does NOT show the matched up pair that DID show up in the test store. (the promo page works fine btw, so i can see that it does not SEE it anywhere).

I re-copied the files 3 times thinking i might have missed one, but no luck. So, where should i look to find the error so to speak?
