I was starting an e-commerce site & wanted to know which cms or script was the best to use. I was looking for something that was... 1. Easy to customize and update. 2. Automatically keeps track of inventory after sales. 3. Has built in S.E.O. features. 4. Secure and not easily compromised. Do any of you know of a WP or Joomla theme, or a certain php script with those features? Thanks.
