Menu
Even though I am running in localhost, my mvc web site gives me this error:
The anti-forgery token could not be decrypted. If this application is hosted by a Web Farm or cluster, ensure that all machines are running the same version of ASP.NET Web Pages and that the configuration specifies explicit encryption and validation keys. AutoGenerate cannot be used in a cluster.
I used this machinekey:
<machineKey compatibilityMode="Framework20SP1" validationKey='AC0DA63E787522E3BA5D47D8FA0A46EB68BB89A35C6353D5E8D3D5CA416D0DA607E56C6D0861ED3B7194C3ED74C0CE79FE4CE2909F34A6CFBDE134C1A094CA40' decryptionKey='A68360896EF374401123C6C222A7AAD8D430DB4DE34938E1' validation='SHA1'/>
But still no use. In addition, I extracted this machinekey from a third party. I know it is not safe but the microsoft way is too complicated: using powershell to generate it? complicated. Then using IIS? My IIS8 is not showing machinekey module. What on earth is going on with all of these stuff.
Okay, maybe the error is caused by a multiple @html.antiforgerytoken. Well, I had indeed two antiforgerytoken, but when I remove one of them, the error persisted.
I am so frustated with this problem. I hope someone will be kind enough to help. I believe those MVC users have been in this situation when developing MVC web site. In my case, I am just a newbie and this is my first MVC web site that is deployed.
thanks for you help

In my case it was caused by the anti-forgery token being applied twice in the same form. ref https://stackoverflow.com/a/28620686/662403
