Hi,
We are also getting both the Error Deserializing ViewState and Cannot decrypt the content. These errors occur together.
- Version 10.0.904.0
- Occurs only on two front-end production servers (not on dev and uat)
- Receiving error in multiple applications
- Error does not always occur with iframe
- Not sure which browsers yet
- Servers are hosted locally
Thanks so much for discussing this issue. We would also like to resolve these errors. Let us know if we can provide more information.
