Hello,
Running into an issue on multiple sites where we receive a "Validation of viewstate MAC failed" error after trying to save changes to settings in the backend. I've primarily seen the error when making changes to security settings but have heard from others it happens with other sections as well. We've tested on a couple different 9.10.12 sites and one that was 9.10.16. An example site would be: https://dev-ccen.mydwsite3.com/
Here is the error we receive:
Thank you,
KC
