Got this just moments ago on a page that simply made the mistake of containing a WebChart control.  I am now having to reset IIS to clear the error, as no users can access the website.  (because I made the mistake of placing a WebChart control on the homepage dashboard).

Using 2011.1, .Net 4.0.  This issue has been documented all the way back to version 2009, and I have reported it several times.

Can someone from IG please take ownership of this issue and find a solution?

Server Error in '/ACISANDIEGO' Application.


Parameter is not valid. 
Description: 
An unhandled exception occurred during the execution of the current web 
request. Please review the stack trace for more information about the error and 
where it originated in the code. 

Exception Details: 
System.ArgumentException: Parameter is not valid.

Source 
Error: 





The source code that generated this unhandled exception can only be 
shown when compiled in debug mode. To enable this, please follow one of the 
below steps, then request the URL:

1. Add a "Debug=true" directive at the 
top of the file that generated the error. Example:

  <%@ Page 
Language="C#" Debug="true" %>

or:

2) Add the following section 
to the configuration file of your 
application:

<configuration>
   <system.web>
       <compilation 
debug="true"/>
   </system.web>
</configuration>

Note 
that this second technique will cause all files within a given application to be 
compiled in debug mode. The first technique will cause only that particular file 
to be compiled in debug mode.

Important: Running applications in debug 
mode does incur a memory/performance overhead. You should make sure that an 
application has debugging disabled before deploying into production 
scenario.
