Severe Problems in Accessing a Website RRS feed

  • Question

  • Hey Guys,

    I am trying to access a website from work and I am having severe issues getting through. Leads to decreased productivity. I have copy pasted the message below. Would love to find a way to solve this problem.

    Server Error in '/GOA.APPRES.Web' 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.

    http://go.microsoft.com/fwlink/?LinkID=314055

    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.
