BillMate has a deprecated constructor (for use with PHP7)

As per title, plugin uses a deprecated constructor method and throws notices when on PHP7.

To solve the issue is easy.

line 32 of /library/Billmate.php now reads:

function BillMate($id,$key,$ssl=true,$test=false,$debug=false,$referer=array()){

change it to:

function __construct($id,$key,$ssl=true,$test=false,$debug=false,$referer=array()){

and you’re set.
