[Defender Pro] MageeWP OneTone Pro Theme coding error

Seems Defender Pro and, or the MageeWP Onetone Pro theme had an issue with an update by The Hub. I am getting a error that is appearing in the public website and the WP Admin section.

the website is nwaautoshop.com

I am at a loss (I don’t code) on how to fix this without wiping everything out. My backups were deleted by Godaddy on server upgrade. 2017 is the closest one that I have.

Thanks,
