I'm running into a problem on OC1.5 and I'm wondering if it's my own stupidity or if the extension just isn't compatible with 1.5 yet.
Fatal error: Cannot access private property Document::$title in /blah/blah/blah/admin/controller/payment/btc_mybitcoin.php on line 35
That line reads:
$this->document->title = $this->language->get('heading_title');
