Help with WHMCS - Negative invoices

nullroute

Hello everyone from this dear forum.

I recently updated WHMCS v7 to the latest release version 8.0.4. And a very strange problem happened:

Whenever a coupon is applied, the problem occurs, the invoice has a negative value and the service is sent without receiving payment.

I've already opened a ticket on whmcs.com but I don't get answers for more than 2 days, has this problem with negative invoices ever happened to anyone? What would be the best alternative to do now?

From the looks of it, your problem is that your 80% off coupon for the 2 2GB plans is deducting more than they actually cost, hence it creating a negative (positive) balance. Fix those two lines to deduct the correct amount and it should be fixed?

The problem occurs in all invoices, it is impossible to correct manually.

Can you please share the coupon page screenshot?

UPDATE:

I still recommend staying in WHMCS v7, the v8 version is still full of bugs.

So basically, adding discount codes (percentage) calculates the discount wrong?

Yes.

True, I regret upgrading to v8 even cron jobs are not working properly when we mark the payment(with add payment option) manually.
