Oops! Nevermind. Looks like I installed it wrong. Everything works!

Glad you got it figured out!

Do you remember what you did to fix it?

I have the same issue on my page. (5.4.1.1)

First, make sure the Background Image attribute got created. Go to Dashboard->Pages and Themes->Attributes. It should show up in the list there. If not, create an Image/File attribute with the handle bg_image and name Background Image. Then, go to a page and put it in Edit mode. Then click on the Properties tab, then Custom Attributes. The Background Image attribute should show up in the dropdown to be added.

I left a message for you on your c5mix site regarding this same subject. Thanks for your answer.

How does "installing it right" have to do with this problem? Is it really a small bug that is easily fixed the way you described or have I actually done something wrong in the setup?

Thanks

Rick,
Just sent you an email about this too, but for some reason the Background Image attribute didnt get created on install, so just follow my directions above to create it.
