I tried to create downloadable product following the documentation I failed in step 3.

My tab with "Downloadable Information" is empty:

enter image description here

I spend a few hours trying to debug this. There is no error in JS console or magento log. I also disabled modules. Cleared cache of course.

Mage_Downloadable_Block_Adminhtml_Catalog_Product_Edit_Tab_Downloadable::__construct() is called but _toHtml() is not (as far as I can tell). I read though related classes, templates and layouts but I could not figure out from where it should be called or what the problem is.

I am totally lost. Any advice where to dig deeper?

Try to enable display errors in index.php:

 ini_set('display_errors', 1);

or add this

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);

Check again if will display any php error. Enable template hints for admin to see which template is showing there . If there is any custom module , disable / debug.


I had the same problem and solved it by enabling a disabled module.

System -> Configuration -> Advanced -> Disable Modules Output -> Mage_Downloadable -> Enable

Then click on Save Config and it might work.
