I have two different sites, both of which are using Joomla 1.5.7 and CB 1.2 RC3. SCM Radio has the gallery and it works perfectly. SCM has the same gallery, but I get the NaN> when it is clicked. I checked the settings on both sites and they are the same. When I turn off SEF, it still shows the popup but with a small picture. On SCM Radio, it does the lightbox display and shows perfectly. Please help me to get the gallery working because I dont want to discourage new members from joining our site because if there is one thing everyone wants is a chance to show themselves to the world!
