We’re receiving quite many of these errors in our logs. When it comes to the GUID in the message they seem to come in pairs.

2021-11-12 05:13:26.1784 [ERROR] [] Litium.IWebLog - IWebLog exception ‘This functionality is unavailable after HTTP headers have been sent.’: f8867ec0-b9fc-400f-8818-9c3da61f28a7 System.Web.HttpException (0x80004005): This functionality is unavailable after HTTP headers have been sent.

I notices that there was a bug, Login, but that’s supposed to be fixed in 7.5.1 and we’re on 7.7.1.

Anyone else have these errors in their logs? Is the bug back?

Litium version: 7.7.1
