I followed the instructions at
http://help.joomla.org/content/view/818/132/ for migrating from Joomla! to Mambo and have encountered just one glitch -- my Event Calendar page (Lamette/McDonell v1.2) is completely blank, and my status bar reads "Done."
I have made sure that every file that was in my \mambo directory but not in the installation copy of Joomla 1.08 is now in the \joomla directory (including all subdirectories).
The administrative parts of the Event Calendar work fine. All my events are there and can be edited. There's just no Event page -- completely blank, not even an error message.

Any ideas? Thanks in advance.
