UPDATE: This plugin can be public by making it a page http://laaatech.com/yourls-page-popular-links
The YOURLS plugin, originally posted here, I have updated to be compatible for YOURLS 1.7.
The plugin shows and admin page of the most popular links created in 1,30,365, and 1000 days on a YOURLS site
Download here, save as plugin.php and upload to YOURLS_DIRECTORY/user/plugins/popular-links
IMPORTANT: Make sure to remove/overwrite the old version of Popular Links if you have it on your server.
At the bottom of the plugin, you can edit the values
1000 means the number of days you are selecting from the database
5 means the number of links you are selecting.
