Render OneAll social login block in a .php file?

Question

I am using OneAll social login module for social registration and login. The module's login block works well on any page but not on a .php file. I am trying to render the block in a xyz.php file programmatically. When I try to render it via the following code I only gets The heading text of the block without the Facebook and Google's links.

$blockObject = block_load('social_login_widget', 'social_login_widget');
$block_ = _block_get_renderable_array(_block_render_blocks(array($blockObject)));
$output = drupal_render($block_);

Check the attached screenshot to see the code output. You can see I only get Login with your Social Network account.
