No customers receipt

Have you looked at the logs of the website when making an order ?
Does the webserver send the emails directly ? Or do you use a third party mailserver ? We need more info in order to help.

Thanks for answering. No, we do not use any third party mailserver, and we use ePay as gateway. Up til recent upgrades the shop has sent customer receipts nicely and without any problems. Now this function has stopped … and I am left in the dark as to why …

Well, at least you’re not on any email blacklists. That’s good to know.
Are you seeing any info in the server log the moment an order is processed ? If you have access to the mailserver, could you see if the messages are queued for whatever reason ? If you don’t have that option, it might help to install the WP-Mail-SMTP plugin. This way you can enter a different email server (for instance a gmail account) to send mail and thereby ruling out any issues on your local (mail) server.

Hello again, I have done as suggested and installed the plugin Email Log.

Email Log says, that after a sale is completed there has been sent a Recieipt to customer and a Transaction Report to me, just as it should be. The problem is, though, that neither of these were received. What is going on?

I don’t know about Email Log, I was talking about “WP-Mail-SMTP”.

OK, I see your point … I shall try on th WP-Mail-SMTP

I have a problem related to this as well.
Since I updated the WPEC to v3.11.3, gold cart to v3.1 and WordPress to 4.5.2 The website admin doesn’t receive the Transaction email sent through to them. They only get the email from Eway their gateway to say that transaction has been accepted.

How up-to-date is the Eway gateway code? It could be that it needs updating – if you stick it on pastebin.com I can have a look.

Make sure you have all the info entered in the store admin settings. The from email/name.
Some email providers can drop incoming emails if they don’t have the sender info setup correctly

Thanks whitelamp and Mihai for your messages.
Eway code up to date. Info was entered in store admin settings.

The store admin settings were set to send and receive from same email. It had been working like this for a long time. The hosting company suggested I try a different “FROM” email address as they’d updated their spam filters lately. I did this and it worked.

The strange thing is that when I changed the FROM email address back to the original address it worked again. All working OK now.

Thanks arenddeboer … your solution works. We now receive customer receipts as we should. Nice.
