How to Install Divi Theme
First of all you will need to download a Divi theme copy from your ElegantThemes account. I suppose you already have an ET account. If not, you can get one here. So just log into your Elegant Themes account and download the Divi Theme package. You should now have a Divi .zip file that has around 8 MB.
Now log into your WordPress admin panel and navigate to Appearance > Themes and click the “Add New” button at the top. Then click “Upload Theme” and upload the Divi.zip file (you do not need to extract it). Click “Install Now” and then click “Activate” to activate it. Voila, you have successfully installed Divi on your website. That’s it for this tutorial.
If this doesn’t work for you, you can also upload the Divi files via FTP (I use FileZilla) to your wp-content/themes/ folder. However, you will first need to extract the ZIP file and upload all files.
Also, I recommend you to use a child theme. You can check my other tutorial on how to create one.
