Hi there, thanks for the ping. It really depends on the specific line and how it’s formatted, per the FAQ area on the admin options page:
This plugin detects a copyright year in the footer to automatically update it to the current year based on a visitor’s location.
For example:
© YYYY
Copyright YYYY
© Copyright YYYY
© YYYY – YYYY
This plugin does not work with this format:
© Company YYYY
Copyright Company YYYY
© YYYY to YYYY
Rearrange text to:
© YYYY Company
Copyright YYYY Company
© YYYY – YYYY

Let me know if that helps or not?
