I'm having a problem accessing iManager. I recently upgrade my eDirectory to 8.8 sp2, and now I can't get into my iManager. I'm running it on NW6.5sp7. All I get is a error saying that the service unavailable and has an error 503 on it.

I've tried TID 7000759, but it didn't seem to work. What am I missing?
ERROR: "503 Service Unavailable" while accesing iManager

Thanks in Advance
