After upgrading to K2 4.7, the system functions properly and K2 Workspace is accessible. However, when attempting to connect to the K2 Management Site and open ViewFlow, the following error message appears. I'm not sure if anyone has encountered a similar situation.

This error indicates that there is a mismatch in assembly/dll version, causing one of the method to be missing “MissingMethodException”.  I would try:

  1. Rebooting the server, perhaps there is a cache or something that is persisting an incorrect assembly
  2. If the issue persists, try a ‘Repair’ to see if the assembly/dll is replaced so that it has the method it needs
  3. If issue persists, a support case may need to be logged
