Upgrade settings not saving

• Add a new user profile field e.g role
• Perform upgrade - all works fine
• Change the user profile field shortname from 'role' to 'Role'
• Perform upgrade and when it reaches the upgrade settings page, it won't save anymore.

New settings - CAS server etc will be looking for 'field_map_profile_field_role' and in database, mdl_config_plugins table field is 'field_map_profile_field_Role'

Go to User profile fields and change the profile field from 'Role' back to 'role' and save works again.

Or change from database directly by running following query

UPDATE `mdl_config_plugins` SET `name` = 'field_updatelocal_profile_field_role' WHERE `name` = 'field_updatelocal_profile_field_Role';
UPDATE `mdl_config_plugins` SET `name` = 'field_map_profile_field_role' WHERE `name` = 'field_map_profile_field_Role';
UPDATE `mdl_config_plugins` SET `name` = 'field_updateremote_profile_field_role' WHERE `name` = 'field_updateremote_profile_field_Role';
UPDATE `mdl_config_plugins` SET `name` = 'field_lock_profile_field_role' WHERE `name` = 'field_lock_profile_field_Role';
