Hi Roman, I think I didnt phrase the title of my issue very well. The problem exactly that when I tried to login into the cms environment it logs me in and almost immediately logs me out with an 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."

You'll have to create a machineKey and add it to your web.config key. You can then upload your web.config via ftp.
