Im working with a Rockettheme-Template ("Firefrog") and this Gallery, which looks great and has a marvelous user interface, is not working. No black screen, no well designed thumbs. The template im using is professionally made. Joomlaworks says on the troubleshooting-Info "Just revert to the default template of joomla". Well, easy to say, but after some 100 hours of developing an individual website with joomla..... Better would be to give some information where on the css changes have to be made. I hope there is a good answer too to that, so I can please our visitors with this wonderful tool too.
