WP Experiments is shutting down.
In November of 2018, WordPress 5.0 will be released. This new version of WordPress brings with it the new Gutenberg editor. Title Experiments relies heavily on the old editor of WordPress and will not be updated to support Gutenberg. Therefore, I have made the decision to stop selling Title Experiments Pro and will not be supporting the plugin on WordPress 5.0+ going forward.
Thanks for all of your support over the years and best of luck.
