Hi Pat, Thanks for your input!
I'm not sure what the error I posted was about. I got that error and a 'cannot allocate memory' error alternatingly. I added swap memory to the cloud server and now the e-com recommender template works! Success :) Thank you very much for all your help. Next I'll see if I can get the UR to work.
