Try this solution:
1. Go on Facebook Developers:
https://developers.facebook.com/docs/plugins/page-plugin#settings
2. In "Facebook Page URL" insert your page instead of “https://www.facebook.com/facebook”
Below these boxes must be checked:
- Adapt to plugin container width
- Show Friend's Faces
Next boxes must be unchecked:
- Use Small Header
- Hide Cover Photo
- Show Page Posts
3. Push the button “Get Code”
4. Save code (one below “2. Place the code for your plugin wherever you want the plugin to appear on your page.”
5. Need to add in the code the following definition: “data-width="YYY" where YYY means dimension in pixels of your desire width of Facebook Like Box block.
For example code for the Facebook page would look like this:
<div class="fb-page" data-href="https://www.facebook.com/facebook" data-small-header="false" data-adapt-container-width="true" data-hide-cover="false" data-show-facepile="true" data-show-posts="false" data-width=”379”><div class="fb-xfbml-parse-ignore"><blockquote cite="https://www.facebook.com/facebook"><a href="https://www.facebook.com/facebook">Facebook</a></blockquote></div></div>
As I said 379 is the width in pixels of your desired Facebook Like Box block.
6. In the file “blockfacebook.tpl” remove code:
<div class="fb-like-box" data-href="{$facebookurl|escape:'html':'UTF-8'}" data-colorscheme="light" data-show-faces="true" data-header="false" data-stream="false" data-show-border="false">
and replaces with the code above.
7. Done J. For me it works, I hope to be your helpful to you.
It is responsive, but please take into account statements made by Facebook:
https://developers.facebook.com/docs/plugins/page-plugin#resizing
“No Dynamic Resizing
The Page plugin works with responsive, fluid and static layouts. You can use media queries or other methods to set the width of the parent element, yet:
The plugin will determine its width on page load
It will not react changes to the box model after page load.
If you want to adjust the plugin's width on window resize, you manually need to rerender the plugin.”
