I gave it a try adding the COWOA plugin on version zencart 155e using westminster_new template by Picaflor Azul.

I don't know what I did wrong but I do not have the option to check out as a guest and also I noticed the my admin panel has change formats. Instead of 3 columns of information, everything is layed out horizontally.

I did go to the config/cowoa settings and marked everything as true.

Any ideas where I should start. I do not get any errors in my logs file.
