Hey Paul,
We’ll be making some updates to the free version in the coming months. I’ll make a note to update the version in the next update, but in the mean time you can change it in the current version of the plugin by opening the following file: wp-content > plugins > custom-facebook-feed > custom-facebook-feed.php and then on line 1950 you’ll see this:
if( !isset( $options[ 'cff_font_source' ] ) ){
wp_enqueue_style( 'cff-font-awesome', 'https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css', array(), '4.5.0' );
} else {
if( $options[ 'cff_font_source' ] == 'none' ){
//Do nothing
} else if( $options[ 'cff_font_source' ] == 'local' ){
wp_enqueue_style( 'cff-font-awesome', plugins_url('css/font-awesome.min.css', __FILE__), array(), '4.5.0' );
} else {
wp_enqueue_style( 'cff-font-awesome', 'https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css', array(), '4.5.0' );
}
}
Change the 4.5.0 to 4.7.0 in the 5 locations you see it.
Let me know whether that helps, or if you have any other questions at all.
John
