Hi,

 

I'm getting 500 Internal Server Error when trying to open a workflow in K2 Designer.

Please see attached image.12684iFA5B709659651344.jpg

 

Can anyone help please on why this error is showing? It's happening on a quite  few workflows that I have.

 

thanks

Aaron

Try to apply the latest CU and FixPack.

    Hi there

    This error can be caused by enabled ASP.NET Impersonation Authentication for Autodiscover under the K2 site.

    View the following link to solve this problem

    If not please let me know of the k2 version you are using

    Regards
