I've found several errors in the latest version...
1.) If you try to update a user profile, you get this error... Warning: Missing argument 2 for save_userzip_data() in marketplace.dev\wp-content\plugins\wpmarketplace\wpmarketplace.php on line 1021
2.) If you utilize the default pages generated by the plugin, and click on product name or edit product, the page just refreshes itself.
But... if you do the same action utilizing the frontend short code it works fine.
3.) There is a CSS issue on hover for all buttons.
4.) When you upload a FEATURED IMAGE from the frontend, there is blank image which displays under the uploaded image, which shouldn't be there.
5.) It appears as though a taxonomy is created for Product Types,the individual product is still displayed a simply... domain/product/productname
6.) If you click MarketPlace in the menu, to goes to a blank page, it would better if this linked to http://domain.com/product since that's the page which displays all products.
In this version I still don't see a place where the store owner, can set the percentage they would take from each sale.
I hope this helps you to correct the issues.
