 * Hello.
 * I thought that W3 was compatible with PHP7.0?
 * I’m getting this error on all my sites, when upgrading to PHP7.0:
 * Warning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a 
   reference, value given in <serverpath>/public/wp-includes/functions.php on line
   3464
 * When will this be fixed? I know there is a fix out there, but it would be nice
   not to have to manually do this on every single site i have.
 * Thank you! 🙂

 * sadly, the author has abandoned this plugin. For me, i’ve decided to fork and
   maintain my own custom version.

 * Oh you got to be kidding me? A plugin with over 1 million active installs?
    But
   seems correct, no updates in 6 months.
 * Well, that’s to bad, guess I need to be looking for an alternative. Got any suggestions?

 * Any chance I could swipe your fork of this plugin? I understand I’d be using 
   at my own risk and won’t bother you with questions if things don’t work.
