Custom Breadcrumbs 6.x.2.x development branch. This is likely to change often and may be unstable for some time. Testers are welcome to try it, but be warned that this is new code and not fit for a production site.
If you are upgrading from an earlier 6.x-2.x-dev release prior to September 30, 2009 you will likely get the following error message when you run update.php.
* user warning: Duplicate key name 'language' query: ALTER TABLE custom_breadcrumb ADD INDEX language (language) in /home/xxx/html/includes/database.mysql-common.inc on line 434.
* user warning: Duplicate key name 'node_language' query: ALTER TABLE custom_breadcrumb ADD INDEX node_language (node_type, language) in /home/xxxxx/html/includes/database.mysql-common.inc on line 434.
* user warning: Duplicate column name 'name' query: ALTER TABLE custom_breadcrumb ADD `name` VARCHAR(128) DEFAULT NULL in /home/xxxxx/html/includes/database.mysql-common.inc on line 298.
You can safely ignore these warnings! The module will work fine after the upgrade. The updates failed because you had already updated your database by using the earlier 6.x-2.x-dev version. Unfortunately, some of the updates in 6.x-2.x-dev had to be renumbered to make the update from the 6.x-1.x branch work properly.
This will only happen to those who have installed a version of 6.x-2.x-dev prior to September 30, 2009. If you uninstall and do a clean install you will not see the error. But that is not required - just ignore and have a great day.
