@developer22, I’m really sorry about your frustrations today. If you think you had it bad, please consider that my user base is some 300,000 users. My support system is under load today.
Anyways, for the folks asking if anything gets tested before release, yes it does. My plugins go out to 30+ beta testers, several live and development sites, plus a multitude of tests are run before any release happens.
In this instance, it’s the fact that most folks are probably running PHP 5.2 which has been end of life for nearly 3 years. This release finally got into PHP 5.3 language specifics.
In any case, more details and fixes are at https://aihrus.zendesk.com/entries/30678006-Testimonials-2-16-0-Requires-PHP-5-3-.
