Cannot add new products
This products was very simple to get started. The DB is up and running. Categories can be added without any problem. But I cannot add any of my products. I keep getting the same error when using the Admin - Insert Products Page: Please enter a valid file (.gif, .jpg, .jpeg, .png). Please enter a valid file (.gif, .jpg, .jpeg, .png). I have tried using .gif and .jog and neither seem to work. Please help!
