Troubleshoot QCMM Checkout, Account Activation, and PayPal

Troubleshoot checkout by separating account activation, local billing state, PayPal environment/credentials, provider capture, and QCMM finalization instead of treating them as one failure.

Start with the Billing Record

Confirm the Plan or invoice, customer, currency, amount due, discounts, tax, Site Credit, and billing status before opening PayPal. If the amount is already wrong locally, fix the QCMM pricing/credit rule before testing the provider.

Guest Checkout Can Pause for Email Activation

Guest checkout may create a Joomla account that must be activated before enrollment/payment continues. The checkout activation handshake is short-lived (30 minutes), and activation-email resend is rate-limited to 60 seconds. An expired activation session requires reloading Checkout rather than forcing a payment record forward.

Verify PayPal Environment and Credentials

QCMM selects separate Sandbox or Live client ID/secret settings and sends API requests to the matching PayPal endpoint. A Sandbox credential in Live mode, or the reverse, is a configuration failure. The checkout heading explicitly identifies Sandbox mode.

Separate Capture from QCMM Finalization

A successful remote capture is recorded before local membership activation. QCMM verifies captured amount and currency against the billing record; a mismatch is preserved as a payment event and automatic activation stops for administrator review rather than silently granting access.

Avoid Duplicate Diagnostic Attempts

If a payment is pending or preserved, inspect the billing/payment-event state before starting another attempt. Browser popup/return behavior, provider capture, and local finalization are separate checkpoints; repeated purchases can obscure the original failure.
