You aren't trying to install both FEC and OPC, are you?
I did try to install just the FEC, that did not work then I tried to install the OPC which did not work either. I did make a backup of my site which I think I will install after I delete the current one on my server.

Yesterday I did a live chat with NUMINIX about the FEC and they said it would work fine on my westminster_new template using zencart 155e. The problem is that I do not know what they mean when they say to Download and install CSS JS Loader first. Maybe this is the problem.
