 Hello,

 Since Wordpress version 4.3 there has been a code change which has
 disabled my plugin for all users that have upgraded (with no error message
 etc).

 Upon investigation, it appears a code change has been made within the file
 'wp-includes/widgets.php' on line 317. "array_key_exists" has been
 replaced with "isset". This requires that the value is not NULL. As my
 widget has no settings (no title etc), the "$instances[ $this->number ]"
 value is NULL and this has therefore resulted in my widget no longer
 displaying.

 Could you please advise whether this is a bug or whether we are going to
 have to change the plugin to store an empty array etc.

 Thanks.
