Default values in forms are invalid
I've noticed that some default values in /usr/local/ispconfig/interface/web/sites/form/database.tform.php have probably been copy/pasted so they contain some bogus default values which make no sense for the given variable. For example:
'type' => array ( 'datatype' => 'VARCHAR', 'formtype' => 'SELECT', 'default' => 'y', 'value' => array('mysql' => 'MySQL') ),
or
'database_charset' => array ( 'datatype' => 'VARCHAR', 'formtype' => 'SELECT', 'default' => 'y', 'value' => array('' => 'DB-Default', 'latin1' => 'Latin 1', 'utf8' => 'UTF-8') ),
These forms should probably be all checked and default values fixed.
