- Hi everyone,
I upgraded my Smartermail 11.4 installation to the latest 12.4.5364 using the guidelines that can be found on http://portal.smartertools.com/kb/a2856/major-upgrade-of-smartermail.aspx.
Since the update xmpplog.log file is getting a log entry every 10 seconds:
23:59:59 ERROR: System.PlatformNotSupportedException: Operation is not supported on this platform.
23:59:59 ERROR: System.NullReferenceException: Object reference not set to an instance of an object.
Does anyone have a clue on how to fix this?
Thanks in advance for replying!
