Stripe payments not working on my site

I switched from Paypal for my payments to Stripe since you guys haven’t been able to fix Paypal’s issue on my site.

Now a user is getting this error when trying to pay:

“No such plan: ms-plan-7559-52eMNnmDcIoQqQogM95HU7; a similar object exists in test mode, but a live mode key was used to make this request.”

I have Stripe in “Live” mode as well as the payment gateway live in my Dashboard. Please help me fix this so people can subscribe to my site. Your plugin is currently unusable for me until I can get this resolved. And I’d rather not pay for something that doesn’t work.

I’ve enabled support access.
