Plugin CT Commerce was built using Scratchpad as base theme, it works better with Scratchpad or similar theme.
Avoid using themes built with Bootstrap ,it conflicts with jQuery UI tooltip used in plugin.
You need to have profile image for product otherwise, plugin will not function properly, (seriously what can you sell with out image?)
After that you need to fill in the shipping field as applicable:
If you are going to use USPS fill in following field, else functionality will not work:If left empty option will not display in frontend
After this you will be able to see bunch of page generated by plugin and a CT commerce menu which will contain basic main featured product page (which displays list of featured products), Product cart page(which displays products cart) and Categories page(which display all of the product categories with active products). You can make this menu Home menu or create your own menu as you wish.Other than Current Discount , other pages are worthless showing in front end they are there to process customer request only(do not delete these pages leave them as is, when you deactivate plugin they will deleted automatically.).
Plugin comes with bunch of useful Shortcodes
