404 Error on product add

General General Questions
1

I have been having some 404 errors on just adding a product to the admin area?

Can anyone assist.

2

I've discovered that if I set the product up with no image it works?

So, can someone explain how I now add the image without getting a 404 error.

Thanks in advance.

Solved. Images were CMYK, adjusted to RGB all working fine!
