So here's what I've done: Loads of customizing using /local copies of /core files. Updated from to 1.9.1.

Now I can't send email. And no, I've ruled out the new >= 1.9 email-queue-through-cron-thingy as root to the error.

When sending invoice updates I get:

Fatal error: Call to a member function addEmailInfo() on a non-object in /xxx/app/code/core/Mage/Sales/Model/Order/Invoice.php on line 885

And this is the same for every email I try to send. New order gives:

Fatal error: Call to a member function addEmailInfo() on a non-object in /xxx/app/code/core/Mage/Sales/Model/Order.php on line 1326

...and so on.

This error occur both in front- and backend. So this has to be central.

And no, it's not the addEmailInfo() that's faulty.

$mailer = Mage::getModel('core/email_template_mailer');

$mailer returns empty, so I think the key is here.

I reiterate that this bit is unaltered Magento core so no custimizations here.

Any clues to what's wrong? Or at least how do I trace this error to it's origin? Or maybe tips where to start looking.

  • What happens if you call Mage::getModel('catalog/product')->load(1) ? Do you get the same "call to a member function XXXX() on a non-object"? Apr 10, 2015 at 12:50
  • If $mailer = Mage::getModel('core/email_template_mailer'); is returning blank / null then this is the issue. I'm guessing you've over-ridden a core file (in local pool) that has since been altered by 1.9.1? Could you list the items you're overriding? Apr 10, 2015 at 12:53
  • @Julien Lachal: I get what can be expected. Or at least not bool(false). It returns a healthy object. At Douglas Radburn: Well, I meant "bool(false)" rather than just empty. Yes, that's what I thought too and therefore deleted/renamed both /core and /local directories. Then copied /core back from fresh Magento install .zip-file. I do however suspect residues from uninstalled extensions, but I never did install any extensions that would tamper with the mailing functions. I think. Thanks for swift answers to you both. Most appreciated! =D Apr 10, 2015 at 13:08
  • I would suggest removing as many XML files from etc/modules as you can, testing, and putting them back one by one to see if one is causing the issue then :) Apr 10, 2015 at 13:24
  • @DouglasRadburn: Thanks! I think I've found clues to a possible culprit. Apr 10, 2015 at 13:30

1 Answer 1



An extension, EA Design PDF Invoice PDF Generator (v1.0.18 - v1.0.20), screwed things up. Connect Manager showed three updates for the extension (within five days). The extension coder probably struggled with Magento 1.9 compatibility ;)

Well thanks Julien Lachal and Douglas Radburn for getting me to think in other directions and thus helping me solve this!
