I understand I'm supposed to upload the Thesis folder somehow into my hosting account. I use Hostgator. The problem is I can't just add the entire folder to (I don't think) to wp-content/themes. It makes me upload one by one, and there are so many files that I'm sure I'm doing it wrong. Am I supposed to add just a certain file? I'm clicking on File Manager, then www...then I go to wp-content/themes and click upload. Your help will be greatly appreciated.
If you're using the latest version, go to Appearance -> Add new Themes -> Upload and upload the zip file.
