Adding theme support for post formats – I get some errors

    Hi,
    I’ve been trying to get wordpress to offer me the option between “standard” and “link” posts.

    I’m using my own custom theme, not based on any default one.

    I managed to get it working in my category template using advice from this thread. Yay.

    But, in order to be able to select a post format in the admin panel, as I understand, I also need to add

    <?php add_theme_support( 'post-formats', array( 'standard', 'link' ) ); ?>

    to functions.php.

    This works, BUT, with errors. It shows me the option to select between “link” and “standard” formats, but when I save the post, I get this error:

    Warning: Cannot modify header information – headers already sent by (output started at /home/public_html/wp-content/themes/2015/functions.php:3) in /home/public_html/wp-admin/post.php on line 237

    Warning: Cannot modify header information – headers already sent by (output started at /home/public_html/wp-content/themes/2015/functions.php:3) in /home/public_html/wp-includes/pluggable.php on line 1196

    The post gets saved correctly in spite of the error, but it is annoying to keep getting it on every content update.

    Is there something else I need to do to get this working right?
    I have read about post formats and adding theme support in the codex but I’m none the wiser.

    Here’s my functions.php:

    Any help appreciated!

    The problem is all of the opening and closing PHP tags that you have. That’s causing the functions.php file to output blank new-lines before anything is supposed to be output.

    You only want to have one opening <?php tag, and no closing tag in the file. As a (very) truncated example…

    <?php
    add_theme_support( 'post-formats', array( 'standard', 'link' ) ); ?>
    remove_filter( 'the_content', 'wpautop' );
    remove_filter( 'the_excerpt', 'wpautop' );

    // Add the rest of the PHP lines here - WITHOUT any tags.

    That seems to have worked! Thank you SO much!
