Hi all, I've got an issue where non-admin users are getting logged out when trying to submit/edit certain grid content. Slightly strange one as I can't recreate the issue with an Admin account, so it seems it might be a permissions issue? I'm getting this 'Could not validate XSRF token' error in the logs with non-admin users: ``System.Web.Mvc.HttpAntiForgeryException (0x80004005): The provided anti-forgery token was meant for a different claims-based user than the current user. at System.Web.Helpers.AntiXsrf.TokenValidator.ValidateTokens(HttpContextBase httpContext, IIdentity identity, AntiForgeryToken sessionToken, AntiForgeryToken fieldToken) at System.Web.Helpers.AntiXsrf.AntiForgeryWorker.Validate(HttpContextBase httpContext, String cookieToken, String formToken) at Umbraco.Web.WebApi.Filters.AngularAntiForgeryHelper.ValidateTokens(String cookieToken, String headerToken)`` Has anyone come across this before? Thanks, Simon
