The only casualty of the transition has been the gallery. Despite my best efforts, I simply cannot get it to act correctly. Add to that the fact that the maintainers of the copermine module for PHPNuke have pretty much abandoned PHPNuke and are no longer supporting it, and that the latest version that was released seems to have been pulled from all sites that had it available, and you have me between a rock and a hard place.
I'm still trying, but the galleries will be down until further notice. I have all the content saved, so nothing is lost. However, I'm afraid I cannot give a time frame for when it will be back up.
