Woocommerce Prepaid Subscription Error

Hello,

We offer a subscription service via Woocommerce Subscription plugin. We also have added the Woocommerce Prepaid Subscription plugin which allows people to either choose to pay monthly, or pre-pay for a year at a time.

The monthly subscription works fine, but the pre-paid option does not work once tax is calculated. The support team for the Prepaid Subscription has pointed us towards our tax plugin being the issue, since the problem is only present when tax is calculated for the yearly amount.

Regularly, it says “$xxx.xx / every year” but after tax is calculated, it says “$xxx.xx / every array”, and people cannot pay at that point, as it says “Error processing checkout. Please try again.”

In order to reproduce this issue, simply select “One Monthly Disc” and then check the box to pay yearly. Once you add a shipping address for a state with sales tax, it changes to “every array” instead of “every year”.

Here is our error log, thank you!
