I have a payment module :
InPay - pay with your online bank
which I would like to update from release 1.0.0 to release 1.1.0.
I read http://www.magentocommerce.com/wiki/packaging_a_magento_extension but when I click “load local packages” I get an error:
“Fatal error: Call to a member function toHtml() on a non-object in /var/www/apps/demo/magento/app/code/core/Mage/Adminhtml/Block/Extensions/Custom/Edit/Tab/Load.php on line 45”
Do I need to create new module with the same name in order to overcome this problem?
