Image effects missing

Hi

I recognized that the image effects (background images) aren't available anymore. There aren't any options to choose. I tried it with 7.0, 7.1 (with and without fluid engine)... Any idea?

Same problem here: 

Try support they say, but how?

I apologise if this is a silly question, but have you added a section background image? Once you do you will see an option for "Image Effects", if you don't see this, then contact support.
