I am fairly new to Magento Development and am having trouble getting a custom shipping module to work. I followed numerous tutorials but ended up with similar errors each time. The current one I am using is here. I tinkered with it a lot but ended up with more errors, so I am currently at the stock of this tutorial copied over to my magento 1.12.0.2 installation.
Under Sysytem->Config->Shipping Methods the new method, Smashing Magazine Carrier, appears and I can edit the values shown. However, whenever I try to go to the cart on the frontend I get the error:
Fatal error: Call to a member function setStore() on a non-object in /var/www/includes/src/Mage_Shipping_Model_Shipping.php on line 421
and the error:
Fatal error: Class 'Mage' not found in /var/www/includes/src/Mage_Core_Model_Resource_Setup.php on line 378
I am at a loss and am looking for any inkling of a right direction to move in to fix this. Thank you for reading! Here are the relevant files:
