You're saying that the new 4.0 version of WordPress helps improve the
"Tinymce-Advanced Plugin". Hosting providers are upgrading or have upgraded the PHP from 5.2 or 5.3 to PHP 5.4.
This is the plugin from Andrew Oz. and it's CURRENTLY NOT COMPATIBLE
WITH PHP 5.4. Please fix that problem before releasing anything. I have posted about this before and you haven't responded.
If you can't fix that issue, no one is going to be able to use it and
therefore your wasting your time.
