I'm having an issue where it says zip isn't installed on this plugin, but zip is installed on my server (CentOS) and shows up in a PHPInfo information.
It shows up in phpinfo as:
Extension Version $Id: php_zip.c,v 22.214.171.124 2008/01/18 00:51:38 pajoye Exp $
Zip version 1.8.11
Libzip version 0.8.0-compatible
I tried to do an upgrade and I've restarted apache and neither made a difference.
