Hi! freedubaiclassified.com is website in asp.net 2.0 with default membership provider. It was fine til yesterday. When i add custom google search box in my website now i am getting the same error Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. I found few solutions in web that if we installed .net 3.5 with service pack1 then we will get such a errors and either uninstall 3.5 or install service pack 2 with Asp.net 2.0 to resolve the issues. ASp.net 3.5 was installed in my pc so that i uninstalled it.but no success. Please advice me a solution to avoid such a problem in asp.net 2.0.
