[SOLVED] Run Umbraco 6.x in Medium Trust / Shared hosting environment

Run Umbraco 6.x in Medium Trust / Shared hosting environment

I have a Umbraco 6.1.5 project, and i want to deploy it to a shared hosting environment. I read that Umbraco 6 can run in Medium Trust, but i cant find much more info than just that one sentence.

And, in the web.config i found this setting: umbracoUseMediumTrust which i can set to "true". But, after doing so, i get the following 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.

Is there anyone who knows how to run Umbraco in such a Shared Hosting environment?

Solution

I addition to setting umbracoUseMediumTrust=true, it should just be a matter of setting the trust and machineKey elements:

<system.web>
    <trust level="Medium" originUrl=".*" />
    <machineKey validationKey="yourKey"
                decryptionKey="yourKey"
                validation="SHA1"
                decryption="AES" />
    ....
</system.web>

You can generate a validationKey and decryptionKey here: http://aspnetresources.com/tools/machineKey
