Problemn with Stripe Notify URL


Brings up this:

Notice : Trying to get property ‘id’ of non-object in /public_html/wp-content/plugins/s2member-pro/src/includes/classes/gateways/stripe/ on line 659

Warning : Cannot modify header information - headers already sent by (output started at /public_html/wp-content/plugins/s2member-pro/src/includes/classes/gateways/stripe/ in /public_html/wp-content/plugins/s2member-pro/src/includes/classes/gateways/stripe/ on line 353

Also getting:

Notice : Undefined index: password1 in /wp-content/plugins/s2member-pro/src/includes/classes/gateways/stripe/ on line 82

Looks like a major issue. Any help?
