Support » Plugin: Disqus Comment System » [Plugin: Disqus Comment System] PHP warnings after upgrading to wp 3.1

  • Getting this on each post listing in wp-admin, under the comments column:

    Warning: number_format() expects parameter 1 to be double, string given in /path/to/wp/wp-includes/functions.php on line 156

    If I deactivate disqus, the error goes away. Re-activate and it comes back. I also uninstalled disqus and re-installed, that did not fix it.

    I echo’d the arg that’s being passed to number_format() and it is indeed a “number” but I guess it’s typed as a string instead of a double.

  • I’m getting the same error. Good insight into the problem. I am working on a work around because it appears that it only affects the admin panel. I don’t want to inconvenience our users, so I have asked our admins to put up with it until I can code a fix. Hopefully Disqus will beat me to it.

    I emailed disqus support yesterday and they wrote back and said they were not seeing the same problem in their tests with WP 3.1. I did some more troubleshooting at their suggestion (turned off all other plugins and removed my custom theme), and it was still happening. I let them know and sent them a screenshot; still waiting for them to get back to me with a 2nd reply. I will post again when I hear something.

    I’m having the exact same problem. It’s something to do with how Disqus pulls comments.

    The actual error is being thrown in /wp-admin/includes/class-wp-list-table.php on line 423:

    echo "<a href='" . esc_url( add_query_arg( 'p', $post_id, admin_url( 'edit-comments.php' ) ) ) . "' title='" . esc_attr( $pending_phrase ) . "' class='post-com-count'><span class='comment-count'>" . number_format_i18n( get_comments_number() ) . "</span></a>";

    And if you replace . number_format_i18n( get_comments_number() ) . with . “N/A” .` you can at least temporarily fix the problem (although I highly recommend not messing with the WordPress core files.

    I hope Disqus can fix this soon.

    My formatting didn’t work there. The temporary fix:

    Replace . number_format_i18n( get_comments_number() ) .

    With . "NA" .

    You can also optionally cast $number to a double in wp-includes/functions.php to temporarily fix the problem.


    function number_format_i18n( $number, $decimals = 0 ) {
    	global $wp_locale;
            $number = (double)$number;
    	$formatted = number_format( $number, absint( $decimals ), $wp_locale->number_format['decimal_point'], $wp_locale->number_format['thousands_sep'] );

    Ok, I have a better fix, ignore the last ones!

    In /wp-content/plugins/disqus-comments/system/disqus.php, go to line 693 (or somewhere near there) and find:

    // Mark entries in index to replace comments link.
    function dsq_comments_number($count) {
        global $post;
    	if ( dsq_can_replace() ) {
    		return '<span class="dsq-postid" rel="'.htmlspecialchars(dsq_identifier_for_post($post)).'">'.$count.'</span>';
    	} else {
    		return $count;

    And replace it with:

    // Mark entries in index to replace comments link.
    function dsq_comments_number($count) {
        global $post;
    	return $count;

    And to be safe, find the function that starts with:

    function dsq_comments_text($comment_text) {

    And replace it with:

    function dsq_comments_text($comment_text) {
    	global $post;
    	$number_of_comments = get_comments_number();
    	return $number_of_comments;

    The problem seems to be in funciton dsq_comments_number, it was returning a bunch of html to format and label the comments which would obviously break WordPress’s built-in number formatting, even if it was converted to a double.
