Attempting to upgrade from version 2.2.1 to 3.0.0 gives the following error:
Adding column CatRoot to Category table...
Error: Can't call method "parent_ids" on an undefined value at /u01/www/cgi-bin/lsql/admin/Links/Table/Category.pm line 431.
Can't call method "parent_ids" on an undefined value at /u01/www/cgi-bin/lsql/admin/Links/Table/Category.pm line 431.
This leaves the current version in a 'broken' state requiring a restore from backups.
