Hi

I'm using mojoPortal 2.3.7.0 and created a Root site and a child site.  Everything on the root site works perfectly.  The child site loads and I can navigate through the pages, but if I try and save some content ( htmlcontent for example) I get the following error:

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.

[HttpException (0x80004005): Validation of viewstate MAC failed.

Not all actions in the sub site create this error.  For example, I can change the  site slogon, but I can't add a new Role administration group.  I can edit a page and add html content, but I cannot actually edit the content.

 I can disable the encryption in the web.config as follows and the error goes away, but so does my security...

viewStateEncryptionMode="Never"

this is a problem when I deploy to a local iis7.5 on my dev machine and my domain hosting account.

My dev machine is win7.

Thanks
