Problem description

or

Fatal error:  Call to a member function setUrl() on a non-object in app/code/community/Unirgy/Giftcert/Block/Adminhtml/Import.php on line 45

Fatal error:  Call to a member function setUrl() on a non-object in app/code/local/Webtex/Giftcards/Block/Adminhtml/Catalog/Product/Tab/Pregenerated.php on line 64

Cause

getUploader()->getConfig() method is replaced with getUploader()->getUploaderConfig() in SUPEE-8788/1.9.3.0, as result some extensions that use it (Unirgy/Giftcert, MagicToolbox/MagicZoomPlus, MagicToolbox/Magic360 or Unirgy/Rapidflow) are now broken.

Solution

Replace getUploader()->getConfig() with getUploader()->getUploaderConfig() in extension code or request a fix from the extension developers.
