The link you followed has expired. Please try again.

Solution

The error “The link you followed has expired. Please try again.” when it occurs during theme upload, it is most likely due to a limitation on upload_max_filesize and post_max_size set by your web host. Please contact your web host to increase these 2 values to at least 32M. Alternatively you can use FTP to upload the theme.

Explanation

upload_max_filesize and post_max_size are PHP configurations that sets the maximum size of a file that can be uploaded. The theme file is 22MB in size and so if the upload limit is less than this number then you will get a link expired error.
