Order process stops at final step

[earthspark]

Upgraded to 1.5.7 c, PHP Ver 7.4 and everything good until the order process throws a 500 error at last step of order confirmation. Error log shows this among other PHP warnings that follow in log:

PHP Warning: A non-numeric value encountered in *******/includes/classes/order.php on line 515.

Here is code from order.php:

    // Update the final total to include tax if not already tax-inc
   if (DISPLAY_PRICE_WITH_TAX == 'true') {
     $this->info['total'] = $this->info['subtotal'] + $this->info['shipping_cost'];
   } else {
    $this->info['total'] = $this->info['subtotal'] + $this->info['tax'] + $this->info['shipping_cost']; //THIS IS LINE 515
    }

I made other customizations to the cart so I am not sure where I went off the rails here. Tax and shipping are not part of price - they are calculated by site owner after order processing. I wonder where to look for problem. Any ideas?

[lat9]

Are there any shipping modules enabled?

P.S. I'm betting that there are other, less severe, logs associated with that checkout. Could you post those (in their entirety) as well?

[earthspark]

Thanks for looking at this. Oh yeah - lots of issues - just thought this might be a jumping off point to a solution.

The only shipping module enabled is flat rate.

The log looks like this:

Are you sure there aren't ANY other logs created during the attempted checkout? You're looking for one that would say "PHP Fatal Error" - warnings don't usually break anything. What payment method are you using when the error occurs? If you enable "moneyorder" payment method and use it during checkout, does it generate the same error? And lastly, if it's an upgraded 1.5.7, check your orders table to see if you're by any chance missing some columns, specifically order_weight and/or language_code - I've seen that go missing during upgrade quite a few times (although this *would* throw a fatal error in the logs).

...

Would you post a screenshot of the flat-rate shipping's setup in the admin's Modules->Shipping?

... an what @balihr said!

Okay, now we may be getting to something. Forgive me for being slow to catch on.

Another log does include the following:

Could this just me an email issue??

Here is the scree shot.

This is the culprit. I suggest you check your php settings to see if ctype extension is enabled. You can go to admin->Tools->Server/Version Info and simply search that page for "ctype" to see if the extension if enabled. If it's not, contact your host to enable it for you. I don't recall seeing it in cPanel's PHP Extensions page, nor in Plesk.

And if it enabled and you're having this problem, I'll just close the door on my way out and hope lat9 or Doc has better ideas. Maybe switching Email Delivery Method to SMTP would resolve the issue?

[lat9]

Looking at the 'stock' zc157c /includes/classes/vendors/PHPMailer/src/PHPMailer.php, I've highlighted line 1791:

        //This sets the SMTP envelope sender which gets turned into a return-path header by the receiver
        //A space after `-f` is optional, but there is a long history of its presence
        //causing problems, so we don't use one

        if (!empty($this->Sender) && static::validateAddress($this->Sender) && self::isShellSafe($this->Sender)) {
            $params = sprintf('-f%s', $this->Sender);
        }
        if (!empty($this->Sender) && static::validateAddress($this->Sender)) {
            $old_from = ini_get('sendmail_from');
            ini_set('sendmail_from', $this->Sender);
        }
        $result = false;
        if ($this->SingleTo && count($toArr) > 1) {
            foreach ($toArr as $toAddr) {
                $result = $this->mailPassthru($toAddr, $this->Subject, $body, $header, $params);
                $this->doCallback($result, [$toAddr], $this->cc, $this->bcc, $this->Subject, $body, $this->From, []);
            }
        } else {

Might I suggest that you review your installation and ensure that the entire /includes/classes/vendors/PHPMailer file-set has been properly installed?

For those pesky PHP Warnings, those are due to your setting of TBA (a non-numeric value) for the Flat-rate shipping's cost.

THANK YOU!

Sure enough, no listing for ctype. Host enabled and issues resolved. Can't thank you enough.
