Excel Services 2010 web part error

  Date: Oct 13, 2011      Category: MOSS      Views: 246
 

I am trying to add an excel web access web part and I keep getting the following
error:
Unable to add selected web part(s)
Excel Web Access: An error has occurred.
Has anyone else run into this?
I can add other web parts on this page with no problem.
I have Excel services configured properly (I think)
Here is what I found in the log file:

Answer #1       Answered On: Oct 13, 2011       

In case anyone is interested, I found the solution (with some help).
The trust level in the web.config was set to WSS_Minimal instead of WSS_Medium.
Changing that made all the difference.
