Good day,
I have added an item with my price $5, whent and created a subscription plan, and added this item. Also created a subscription for a customer. But when I click Fetach Subscription Updates an given this Message Error

Incorrect value: Grand Total (Company Currency) must be >= 0.0

Please help. My company has a currency, the product has the price. Try to google this but am getting nothing.
Thank you

I managed to overcome this by just unchecking Prorate in the Subscription Settings
