I did see that but I can’t find the functions.php file. I did dashboard-appearance- but I don’t have editor option.

Do you have FTP access to your site?

Someone created the site for me. A child’s theme based on Genisis. I have admin privileges but for the life of me I can’t find the FTP. Is it possible that I don’t have access? Thank you for your patience. I know this is a basic skill question.

Someone else had mentioned using this plugin: https://miwisoft.com/wordpress-plugins/miwoftp-wordpress-file-manager

Perhaps it could help. I am not familiar with it however.
