Unexplained errors
Hi
We recently launched a Sitefinity site (4.1.1395.0) and whilst mostly ok we are getting unexplained errors:
This one happened after one of the admins edited an existing page title and published the page: On publish the whole site broke with this error:

Hi Nick,
There was an issue in 4.1 SP1 which seems to be related to your scenario and has been fixed in 4.1 SP2 ( build 1501 ). In order to be sure that this is the same issue, please look for the following line at the bottom of the stack trace when you get one of the exceptions:
Telerik.Sitefinity.Security.SecurityManager.UpdateCookies
If you can see the line ( if you don't please make a screenshot of the full stack trace and attach it to your reply ) it means that you are encountering the bug we discovered in 1395 and was fixed in 1501.
Kind regards,
Victor Velev
