This release addresses a security issue discovered by Secunia Research. We thank Secunia for alerting us of the problem. At the same time we apologize to Pligg users who might have to make a second upgrade after the recent 1.1.0 release. The good news is that the upgrade process from 1.1.0 to 1.1.1 is very simple.
The 1.1.1 version fixes a couple issues that were discovered in the previous 1.1.0 release, in particular a fix for RSS feeds, and a bug that caused sites to show blank pages after a successful installation.
One modification recently made is that the “Top Users” page will now sort users by karma score in descending order. Previously this page displayed all users and sorted them by username in ascending order. The page will now hide any users with a karma score of 0 or below (negative karma), punishing inactive users. In order for your site to benefit from this change you must run the /libs/karma.php file using a cron job, or your web browser, regularly.
The upgrade process from the previous 1.1.0 release is very simple. Just copy the new 1.1.1 files over the previous 1.1.0 files, overwriting the older files. When that completes run the upgrade script from /install/upgrade.php to update your Pligg CMS version number and complete the upgrade process.
With the exception of the template_details.php file version number updates, there have been no changes to the template files between 1.1.0 and 1.1.1.
