I get the errror message "An unexpected error has occurred. Please contact the webmaster." after having unpacked the distro and trying to run it on my localhost. The error log says:
[ Sep 07 2010 10:38:22 ] Unexpected error, the message was : Unable to
connect to the database server 'localhost' in
/Applications/MAMP/htdocs/ezpublish-4.4.0-beta2-with_ezc-gpl/lib/ezdb/classes/ezmysqldb.php
on line 164
In the middle of fixing it, but basically as a workaround you'll need to setup connection parameters to db in settings/site.ini. Table is not needed, but you'll get a notice during setup if it is wrong.
[Update] Alternative: While we wait for new packages, overwrite index.php and kernel/classes/datatypes/ezuser/ezuserloginhandler.php from git master:
