I am looking to change the link of my facebook button but i can't find where to do it. I have looked in item.php and don't see where I can do this. Any help would be appreciated

You can simply look for "facebook" or fb inside item.php, you will find it then.

Hi Krikor,

Thanks for your quick response.

I'm sure I'm missing something simple but I have searched 'facebook' in item.php and all i find is 'facebook button'. Can you please show me exactly where I can put my facebook url in so i can link it to my facebook page?

OK I'm pretty sure I figured it out...
I'll put it on here in case anyone else is having trouble with the same thing

In item.php on line 329 you can find
"<div class="fb-like" data-send="false" data-width="200" data-show-faces="true"></div>"

To link your facebook like button from your website to your facebook page change the code to look like this:
<div class="fb-like" data-href="YOURFACEBOOKURL" data-send="false" data-width="200" data-show-faces="true"></div>

I hope this saves someone the time it took me to figure it out :P
