    I wanted to show the post format icon on homepage. I am using font awesome to add icon. Everything is showing fine. On local server there are no errors. But after I have uploaded to main server its showing these errors. Its showing when I update any post.

    What happened ? and How I can solve this. Please help.

    Here is the demo site link

    This code is on line 3:
    <?php if ( has_post_format( 'audio' ) ): ?>

    Note: There are no white space before php tag
