I just got an error message on my sharepoint. it does not give any clue, the message in the display is so useless. Then, i am trying to find the log which is usually located atAnd again, such a useless log, not telling me anything about the cause.
However, I can delete the problematic webpart by specifying this parameter ?Contents=1 For microsoft, this may be called a hidden secret. They dont want to spread the knowledge on their product. Such a stupid.
Also, Sharepoint has an administration page, it is a different process which runs in the different port... haiiihhh.... it is running on port 42094
