I just update the plugin and after that I got this:
Deprecated: Assigning the return value of new by reference is deprecated in /var/www/vhosts/site.com/httpdocs/wp-content/plugins/w3-total-cache/lib/W3/PgCacheFlush.php on line 389
So there is a conflict.
Every time I go to the plugin and save something, that shows up again.
Is there something to do to fix it ?
I know its W3TC the one with deprecated code, but this plugin is triggering it.
