TOTP 2FA rollback to Local Database

[FATeknollogee]

Since I messed something up & have locked myself out, I'm trying to reset root pw & rollback to local database.

I follow this procedure: https://protectli.com/kb/how-to-reset-the-opnsense-root-password/
>>> Do you want to set it back to Local Database? [y/N]:y
After changing the root pw, I get this error message:

PHP warning xml failed to open stream....read only file system in /usr.....php

The system will not rollback to local database.

Any ideas??

My fault, I was typing something wrong, all is well.
