After upgrading to plesk 9.53 we are getting the following error with .Net sites - nothing else has been changed on the server:
Server Error in '/[appname]' Application.
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.
OR
Server Error in '/[appname]' Application.
Object reference not set to an instance of an object.
Please advise of how we can fix this - what does Plesk 9.53 change in relation to .Net?
thank you
