"The link you followed has expired" when uploading the theme.
If you are installing your theme from the WordPress theme installer, but get a message that says "The link you followed has expired" most likely 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. The theme ZIP is bigger in size. 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 upload_max_filesize 32M.
- You can upload your theme via an FTP client.
You can verify your PHP configuration limits by installing a simple plugin called WordPress phpinfo().
Recommended PHP configuration limits are as follows:
- max_execution_time 600
- memory_limit 256M
- post_max_size 32M
- upload_max_filesize 32M
