00359: Password can not be reset
Description: Default password can not be reset to '' in farmconfig.php - well, resetting it has no effect. Resetting to an alternative encrypted password also has no effect. BTW, upgrading is not an opetion - I have two very complex v1 wikis.
What do you mean by "can not be reset..."? Are you attempting to undo the effects of any default password set by a field in a field's config.php?
If so, you may need to do the following in farmconfig.php:
$DefaultPasswords['admin'] = '';
This causes the local (field) settings to be parsed immediately, and then they can be changed by the farm.
