Response from envato:
Unfortunately your submission Product - Joomla Directory and Product Showcase isn’t ready for ThemeForest and cannot be resubmitted as it did not meet our minimum requirements for quality and/or Envato Market policies. In order for submissions to be considered for sale they must be of high aesthetic and technical quality, unique to our library and cannot be in violation of Envato’s policies.
