    Issue with the plugin on 3.9 with iTheme2 template. Getting the first error “undefined constant” at all times on all pages (debug mode) and getting ALL of the errors when submitting a post.

    Notice: Use of undefined constant adcopy_wp_enable_comment_reply_reload – assumed ‘adcopy_wp_enable_comment_reply_reload’ in /home/***/public_html/wp-content/plugins/solvemedia/solvemedia.comment.inc on line 25

    The page does not load and just kicks out the errors above.

    Resolved.

    For those who are having the same or similar issue, it has to do with the output_buffering setting in your php config. There are 2 methods that I know of to get rid of it without re-writing a bunch of code.

    1.) Try to force a buffer on the page(s) in question (comment.php and pluggable.php)

    At the beginning of the file add:
    <? ob_start(); ?>

    and at the bottom of the file add:
    <? ob_flush(); ?>

    2.) Enable output_buffering in your php.ini or php5.ini file

    Add:
    output_buffering = On

    OR if you want to allow buffering only up to a certain size (better option), specify it (in bytes):
    output_buffering = 4096
