The version 4 rollout is a bit of a disappointment. A few good features have been added. However, the hide backend feature breaks front-end ajax functionality which was fixed back in version 3.0.10. That affects WooCommerce, numerous Event calendars and likely hundreds of other plugins in the WordPress.org repository based on a simple search of "ajax". The ability to manually clear log files has also been removed, requiring users to resort to other means to clear the itsec_log table. We're indifferent on the changes to the interface, but can understand why some people don't like it that all settings are on one tab.

We think Chris Weigman's work on this plugin is generally terrific and expect the issues we've identified along with those identified by others will get resolved quickly, but we're sticking with version 3.6.5 for now.
