hi,
That error code and the all.js belongs to "facebook.com". So i can't give you support about it, because i have no idea.
Our VM Template uses
official "Facebook Like Button" that has been generated from:
developers.facebook.com/docs/reference/plugins/like/
The facebook like button (within our VM TEmplate) only shows off on the product details page. If you take this screenshot from an another page (etc. category browse page) then it means, one of your another 3rd party plugin is trying to load the facebook plugin which is irrelevant to our VM Template.
But if you took that screenshot from the product details page, the reason of it might be the facebook like box we have used. You may revise that facebook like box through the official developer URL of facebook.com and insert your own HTML lines instead
We have copy-pasted the "iframe" format and put it in the product details page, which is here:
/templates/YOUR_TEMPLATE/html/com_virtuemart/productdetails/default.php
(or flexv2.php whatever page layout you are currently using)
Through the facebook like button generation page, you can take the HTML5 or XFBML formats. (the installation is little different for them, while iframe is just easy because it is based on copy-pasting 1 single HTML element)
Facebook explains how to integrate the HTML5 and XFBML to your website, you can take a look at their tutorials. OR you may completely eliminate the facebook like box and use a 3rd party extensions to achieve "LIKE"; something like
www.addthis.com or
www.sharethis.com (there are also others, search it through
www.google.com)
Regards.
