If you are installing your theme from the WordPress theme installer, but get a message that says "The Link you followed has expired", this means that your web server is configured with PHP settings that are too low to allow the theme ZIP file to upload. Specifically, PHP is configured to a maximum file upload size limit at 8 megabytes or less. Thus, the web server is rejecting the upload. WordPress is giving you a rather ambiguous message in response. This is not a theme fault or bug.

There two ways to solve this problem.

• You can either get your web host to increase your upload_max_filesize to 32M. Here is the guide: https://www.wpbeginner.com/wp-tutorials/how-to-increase-the-maximum-file-upload-size-in-wordpress/

• Alternatively, upload the extracted theme package via an FTP client to wp-content/themes directory.

Recommended PHP configuration limits are as follows:

• max_execution_time 60
• memory_limit 256M
• post_max_size 32M
• upload_max_filesize 32M

They are required for dummy data installation.
