The egroupware package bundled with Plesk wouldn't work at all on my new Suse 10.2 box. I tried the yast distro, same thing, no joy. I finally got the source rpm to work, or so I thought. I had everything setup, had done several reboots. So today I decide to put the egroupware in use and, tada! Nothing. All the pages come up blank. Can someone give me an idea how to troubleshoot this?
