Today I upgraded my website to Joomla! which is a "rebranding effort" and not a fork of Mambo. Version 1.0.3 is quite similar to Mambo 4.5.2.3 and the update is quite painless.I also upgraded my server with PHP 5 and MySQL 4.1. Not all Joomla!/Mambo components and modules seem to be compatible with PHP 5 yet. I corrected one problem in DocMan and hope you will not meet other issues while surfing on this website.
