Hi-
At first, thanks for the plugin.
With version 4.6 is the function wp_get_sites() deprecated and you should change a little bid. I develop always on the last nightly and I have change this.
Funktion mkEndPoint() in EzPlugin.php, line 47, switch to the new function get_sites():
if (function_exists('get_sites')) {
$info = get_sites();
if (!empty($info[1]) && $info[1]->path == "/") {
Thanks.
