Hi @featherstonej ,
There would be a way to undo this through either a configuration or database setting, however, unfortunately that goes far beyond my experience. At a general level I would suggest looking for a configuration or settings table and then familiarising yourself with that. If you have a backup of the database you could spin up alongside you could potentially do some comparisons from before and after you made the settings change and that may help point you in the right direction also.
Apologies that I can't be of more assistance.
