Hi Knuckle101
That EXPECTED_PRODUCTS_SORT is only in zencart /modules/upcoming_products.php they are in the database as config values.. you must only have a partial install of the database config table values..,

I'm actually posting because there seem a lot of people not getting the product image cached.

Mine works ok once the cache bmz folder is 777 or equivalent - but also..

Check that you have
Code:
    if (function_exists('handle_image')) { ...
in your functions/html_includes.php

Older versions of that file may not have that code block (it's in the 1.3.5 version file), which activates the image handler, in it. I got caught out because I had modified my older html_includes.php and added it without merging to include the 1.3.5 image handler code.
