Hi,
I have created a k2 blackpoint process using a webbased InfoPath form. When I try to submit the form I get the following error in SharePoint Logs (no log entries in K2 log and event viewer):
---------------------------

---------------------------------

When I submit the form using InfoPath client it is working correctly. I think there is some authorization problem. The user who submits the form is site collection administrator and local administrator.
Thanks for your help.
