Critical error: Subscriptions are not renewing!

(@obiplabon)

Hello @krzysztofskorupa

We are facing a critical error with subscriptions! All the subscriptions were working properly before the last update and we’re noticing a critical error after the update. We suspect that the error might be the reason for not renewing the subscription automatically. I’ve attached all the details below. Could you please take a look let us know how to solve the issue?

Best regards

Hello,

Thank you for reaching out to us. It looks like PayPal’s integration expects subscriptions to be instances of the WC_Subscription class (from the official WooCommerce Subscriptions plugin). Our plugin uses its own type of subscription object, which leads to a critical error when PayPal tries to process automatic renewals.

I’ve already passed this issue to the development team responsible for Flexible Subscriptions.
They’re now reviewing the necessary changes to improve compatibility and avoid this error in future releases.

I kindly ask for a bit of patience — i’ll inform you as soon as a fix is ready or if I need anything further from your side.

Thanks again for your cooperation.

Best regards,
