I'm surprised not many others have noticed this bug as well.
When you add a new product, you get an error..
Here's how to fix it:
Open image_inc.php and remove
Content visible to verified customers only.
I got this same error, and the above fixed it. I figured I was the only one who got this error, so I fixed it on my server.
This error should be on everyone's install. I don't even know anything about a buddy feature in reviewpost.
