I turned to eShop after DukaPress stopped working. I must have a plugin installed that conflicts with the DukaPress, but not so much with eShop (and it's not a plugin featured on the list of known unfriendly ones).
When I click on Stock Available, there is no Stock Quantity field that appears for me to fill in, and upon save, I receive the error message that a field needs to be filled in to complete adding this item as a product. Any suggestions? I'm going to look into the plugin code and see if I can tweak anything.
I have a simple custom WP theme, with the following plugins activated (and others installed) on the version of WP before 3.1.1: Google Analytics, Google Maps mad Simple, Contact, Image Scaler, Search Everything, Simple Image Grabber, SexyBookMarks
Thanks for your help, a point in the right direction would be a great help.
