    StartIndex cannot be less than zero.

    I upgraded Umbraco from 4.7.1 to Umbraco 4.11.10.  Everything seems to work fine except, if I go to a start node that doesn't exist, it doesn't show the standard 404 Not Found page.  Instead it shows:

    StartIndex cannot be less than zero.
    Parameter name: startIndex

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: System.ArgumentOutOfRangeException: StartIndex cannot be less than zero.
    Parameter name: startIndex

    Source Error:

    An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

    Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18446

    However, if I go to a subnode that doesn't exist, I get the 404 Not Found page that I would expect.

    So, mydomain.com/page - StartIndex cannot be less than zero

    But, mydomain.com/page/page - get standard 404 error page

    Any thoughts?

    Hi Jennifer

    Did you go straight from 4.7 to 4.11?

    And does the site contain any custom Umbraco API integration? Are there any possible 3rd party packages issue? MNTP issues?

    Have you checked the /app_data/logs folder to see if the log file reveals anything?

    /Jan

    I have seen this before when a property type has been changed from either a string/mntp to a boolean.

    As Jan says i would check the logs and see what is throwing the exception :)

    This page indicated that the problem could be with Autofolders: http://stackoverflow.com/questions/20586338/startindex-cannot-be-less-than-zero-showing-instead-of-404-page

    I removed: <notFound assembly="AutoFolders" type="NotFoundHandler" /> from the 404handlers.config – it resolved the issue, I added it back in, but placed it at the end of the config file instead of the beginning. It appears to be working fine.
