I tried deactivating and also deleting the plugin, and then re-uploaded it and activated it and the duplicate products are still there.
I even went into PHPMyAdmin and dropped the tables for eShop, deactivated the plugin, deleted it, reuploaded it and reactivated it, and the duplicate products are STILL there! If I dropped those eShop tables from the DB how in the world could the products still be listed?
At this point I would like to just have a FRESH install of Eshop with no previous data and then start from there to see if I still have a problem. I would be happy for you to FTP to my server... just need a way to get that info to you in a secure way.
