"Link I followed has expired" when trying to add plugin for upgraded website template

Hello!
I am just beginning to learn word press so I chose to use a one click install template to get me started. I downloaded an upgraded template to my computer. When I try to upload the zip file and add the plugin it keeps saying “The link you followed has expired”. I’m looking for some advice to fix the problem.

Thank you everyone for the help!

That error is a custom WP error that hides the actual issue that the website is having. The most common reasons for receiving this response are deficient PHP memory and execution settings.

The failsafe solution for uploading entire themes is to simply upload using an SFTP client. In a standard WP installation the target directory is /home/<user>/<domain>/wp-content/themes/
