We are using version 1.2.3 of module M2MetaTagsTemplate on our site. When using template '[product_description]' and description set config 'Use Default Value' in the Scope Storeview, we are facing an issue 

The issue just happens with the product without Description.


To solve the issue above, we have modified this file app/code/Bss/MetaTagManager/Helper/Data.php

Please apply this file to your site to fix the issue.

If you have any issues, please feel free to contact us.

We'd like to help.
