Downloading The Installation Files From ThemeForest
The first thing to do is to download the installation files from ThemeForest. There are two packages available, as you can see in the screenshot below – All files and documentation, and the Installable WordPress file only. The Full Theme Package has additional files such as the Child Theme zip, plugin file, demo data files, history version file, while the Installable WordPress file contains only the files you need to upload to WordPress.
- Log in to your ThemeForest account and navigate to your ‘Downloads’ tab and then locate your Arnold theme purchase.
- Click the ‘Download’ button and choose to either download the ‘Installable WordPress file only’, which is just the WordPress installable file, or choose to download ‘All Files & Documentation’ which is the full file package.

Extract the package file
After extract the main zip file, you’ll see these folders and files:
- arnold2.zip – Arnold theme(latest version) installable file
- arnold2-child.zip – Child theme installable file
- plugins folder – The plugins installable file
- version1(for-existing-users) – The Arnold theme version 1.x installable file(for existing users only)

2. If “The link you followed has expired.” is shown when you upload the zip file. It may be caused by upload size limitation, please increase the PHP configuration:
post_max_size = 64M upload_max_filesize = 64M
