I receive the following error as a click on any item in the
treeview. I'm using IMAP and it's running on Windows.
If you need exact versions let me know.
PHP Fatal error: Unknown(): The script tried to execute
a method or access a property of an incomplete object.
Please ensure that the class definition treeview
of the object you are trying to operate on was loaded
before the session was started in D:\groupoffice-
