So I was FINALLY able to fix my site thru the FTP client. It took forever and I hope no one else ever has to go thru that like I did. BUT, in case you do, once you log in to the FTP folders the file path to find the “Functions,php” file that is referenced in the article above is this:
https://YOURWEBSITE.com/home/YOURUSERNAME/YOURWEBSITE.com/wp-content/themes/YOURACTIVETHEME/functions.php
And you can just follow the steps in the artcle.
Thanks again to Santeven for their simple, yet helpful, advice.
