<solved>Fatal PHP Error Detected - index.php?route=checkout/register/save

OC 3.0.3.6
PHP 7.3.33

I got this error reported by Lightning:

Referer: index.php?route=checkout/checkout
Uncaught Exception: Error: (0) in system/library/mail/smtp.php:90

And I had a complaint from a new customer that the web site crashed or something on him when he tried to check out a product. I tested and it seemed to work, and I've had other orders completed overnight and this morning. And that order showed up about an hour and a half after I posted the previous sentence and after I had checked PayPal for it. Very weird!

(added later) Just now (noonish) I got a call from a customer who made an order - paid with PayPal, I can see the payment on PayPal.com - and the order DOES NOT EXIST on my site! No new error messages either! Crap. Something is broken...grrr.

Any ideas?

Thanks,

PS, for some reason I couldn't use the function menu items - Bold, Quote, etc...(Firefox 115.8.0esr)

Missing IPN from PayPal due to network issues? Check your server's raw access log.

What is very strange is an hour after I posted the extra sentence about a customer who didn't get confirmation of an order going through (nor did he show up in my system) I got a note from PayPal saying we have an order! At which point the customer's information was now showing in the system.

I wonder if this has anything to do with caching? I haven't made any adjustments to the site for a while though.

PayPal can be quite slow at times sending IPNs because of network bottlenecks.

In other words, don't worry about if a transaction went thought unless it doesn't show up that day...I'll remember that in case it happens again.

Any thoughts on the Fatal PHP Error? I don't think they are related, and I really should not have put them together - that doesn't help anyone!

Your OC admin email settings aren't configured properly from your settings > edit settings > mail tab.

Hmm, well I thought I had it correct:

Mail Engine: SMPT
Mail Parameters: (none)
SMTP Hostname: ssl://mail.xyz.com
SMTP Username: username
SMTP Password: password
SMTP Port: 465
SMTP Timeout: 5

I haven't seen that error reappear on Lightning mind you, so perhaps it was a bad communication to my ssl email server? I am getting emails sent from OC after all.
Perhaps I should increase the timeout?

Thanks for your time!

A 5 second timeout could be a little low for some SMTP servers. Unfortunately OpenCart will fail on an order for any SMTP error.
If your settings are correct and you don't get the error for every email sent then this topic has some workarounds. viewtopic.php?t=230461
