I am using 1.3.9 and have successfully added the contribution for attribute pop-ups. It does exactly what I need. I have one periferal problem however. Somehow I have lost my left sidebar and I cannot figure out why. In the config for my admin it should show. I switched off the template and it reappeared.

I am wondering if the attribute popups could have that effect somehow?
