Error: Your subscription expired, please renew it

I got this error out of a sudden while using your plugin: [3-Oct-2023 19:08:18 UTC] Failed to generate content using AI writer: text-davinci-003 - error: Error while processing AI response: Error: Your subscription expired, please renew it. I am on your Paypal auto subscriptiono scheme and my last payment was Sept 3. So I guess it is you missed to pay to OpenAI. Whatever the problem, kindly let me know when it is fixed. Thanks.
