    Needless to say I'm LOVING the Wordbook plugin. It works, but upon hitting 'Publish', I get a white screen with the following error:

    Warning: Cannot modify header information - headers already sent by (output started at /home/*******/public_html/wp-includes/post-template.php:79) in /home/*******/public_html/wp-includes/pluggable.php on line 390

    Any help would be GREATLY appreciated :)

    This error message typically appears when a script tries to do a PHP Redirect in the middle of (as opposite to "in the beginning of") an output. I don't know the specific plugin...

    If this is only occuring when the WordBook plugin is activated on your blog, then your first step is to check (all) the php files for that plugin and make sure this:


    is the very first line in each, and this:


    is the very last. That means no empty lines or spaces before (<?php) or after (?>). For more, see:

    I checked the wordbook plugin, and the ending php tag was missing, and there were spaces after some of them in the files so I corrected that.

    The error still occurred, so i corrected that in the file mentioned in the error and still no go.

    The line the error mentions has this on it:

    $content = str_replace(']]>', ']]>', $content);

    Any ideas?
