Please read first the bug report at:
This script removes dupe entries in the ezkeyword table and the
ezkeyword_attribute_link table.
Apply first a patch to remove the bug.
Please make a backup of your database first!! (Use the script at your own
risk!!)
Then place the script e.g. in
update/common/scripts/ezkeywordupdate.php
Call it in your main ez directory like
php -C update/common/scripts/ezkeywordupdate.php -syour_siteaccess
Kind regards,
Georg.
