Server Error in '/' Application.
--------------------------------------------------------------------------------
Validation of viewstate MAC failed. If this application is hosted by a Web
Farm or cluster, ensure that <machineKey> configuration specifies the same
validationKey and validation algorithm. AutoGenerate cannot be used in a
cluster.
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.Web.HttpException: Validation of viewstate MAC
failed. If this application is hosted by a Web Farm or cluster, ensure that
<machineKey> configuration specifies the same validationKey and validation
algorithm. AutoGenerate cannot be used in a cluster.
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.
