This KB walks you through configuring the timestamp format used by K2 while creating those vital log files – helps with debugging. The config file to modify is HostServerLogging.config (lives under host server\bin\) and the setting is: <add key=”DateFormat” value=”yyyy-MM-dd HH:mm:ss” />
Here’s a Gem for you. A Nice pdf that walks you through the details on permissions required for the K2 for SharePoint piece. The core of this information is also available in the help documentation for K2 4.5. But, this is a must read for everyone looking at installing K2 on a SharePoint environment.
K2 released a beta recently to Provide Support for SharePoint 2010. This beta requires the latest update KB1140 for the 4.5 platform. You can download it from the customer portal. Both Sharepoint Foundation and Server are supported for both blackpoint and blackpearl with this Beta.
