Why am I having this problem adding a category?
Today, I just downloaded and set up my first Commerce Kickstart site. I added a product type to the site. But when I go to add a product, it does not show the product type I just added, which I don't understand. It only shows the default product types (Bags & Cases, Drinks, Hats, etc.).
I thought I may need to add a category, but when I click the Add categories button, I get an error message that fills the screen and says "Additional uncaught exception thrown while handling exception." It is followed by a heading that says "Original" with some code underneath and another heading that says "Additional" with more code underneath. It's all in black text on a white background.
Can anyone help me with this?
