Hi Richieeee,
It is not really a rename option unfortunately, you would need to run SQL queries to rename an account group I think just add the new account group say "new_account_group"
then run the following SQL from say phpMyAdmin or other mysql client:
Code:
UPDATE chartmaster SET group_ ='new_account_group' WHERE group_ ='old_account_group';
edit: The point has been made to me off list/forum that this does not work (thanks Tim) when old_account_group is also a parent account group, you would also need to run
Code:
UPDATE accountgroups SET parentgroupname='new_account_group' WHERE parentgroupname='old_account_group';
