Hello,

I've got an issue with out Umbraco 6 based website.

When I try to login to the CMS, the page briefly flashes then displays the login page again.

The website itself and all related backend content is displayed with no issues.

OS: Windows Server 2019 Web Services: IIS 10 .NET Framework 4.0

copy and paste from Umbraco Log

2021-12-06 15:02:13,642 [8] INFO umbraco.BasePages.BasePage - [Thread 21] User admin (Id: 0) logged in

Worth pointing out that when I enter a password I know is not correct both the username and password box are highlighted red.

I have checked the database and both the userDisabled and userNoConsole settings are 0 (False)

I have changed each of these two settings to 1(True) and back with attempted logins between changes, but still the same issue as above.

Any advice or help would be greatly appreciated.

Regards

Craig
