I went through a host of troubles of trying to upgrade from 9.8.2 to 9.9 and unsuccesful of doing so. I reverted back to 9.8.2 and restored the old db. Sigh... I wish some day pligg makes upgrade a lot easier. Like one push button upgrade.
. For now I can't upgrade due to the trouble I went through... You can check out the other thread of mine related to this in bug reported area at
pligg 9.9.
