Brief
We have returned the original functionality for Google Export buttons.
 
Description
"Google Merchant Center Export" button doesn't export all products anymore.
"Google Merchant Center Filtered" button exports only the products selected with a check mark while before it was exporting all products from the current category.
 
Solution
Download the updated version of the file:
http://www.viart.com/downloads/admin_items_list-4.html.zip
 
Further, extract the 'admin_items_list.html' into the 'templates/admin' folder of your shop replacing an existing file. Please do not forget to make a backup copy of the current file in case something goes wrong.
