Re-zipping or extracting theme from wordpress site files

The easiest way to do this is to upload them using FTP. You can use a free program like Filezilla to upload your files to your server.

You will need to know the host name (usually just your domain), user and password. If you don’t know this info your hosting company will be able to assist you.

Once connected, find the folder where WP is installed. This is typically inside of /public_html/. Your theme files are located in /wp-content/themes/avada/. You can upload your backup there.

I would make sure you have current backups before doing anything.
