Most issues are caused by incorrect credentials, missing/blocked callback URLs (for HPP), or caching/optimization on checkout pages. Check order notes/logs for the exact message, fix the setting, then try a test order again.

• Confirm the method is Enabled in WooCommerce → Settings → Payments.
• Check store Currency/Country support with your acquirer.
• Verify shipping/tax rules aren’t hiding payment methods.

No settings appearing in Payments

• Deactivate/reactivate the plugin.
• Ensure no role/capability plugin hides Woo settings.
• Clear admin cache and reload.

HPP returns but order doesn’t update

• Verify callback URL: https://YOURDOMAIN.com/?wc-api=wc_gateway_powertranz
