 * First, I would imagine it is a problem and two, how do I fix it. If there is 
   info I should be looking at instead, I would be happy to.

 * Or the problem could be that not all WordPress files are uploaded and intact.
 * Review [Uploading WordPress to a remote host](http://codex.wordpress.org/Uploading_WordPress_to_a_remote_host)
   and make sure you are using ASCII tranfer mode.

 * hi all:
    all fixed now. MY FIX below:
 * my error message said:
    [08-Jan-2009 10:46:08] PHP Warning: Cannot modify header
   information – headers already sent by (output started at /home/worldpea/public_html/
   fabradio/wp-admin/includes/template.php:3451) in /home/worldpea/public_html/fabradio/
   wp-includes/pluggable.php on line 850
 * so i opened template.php in editor and deleted space after the last line in template.
   php
 * and now it works

 * quikone:
 * looking at your error message … to me this indicates that you most probably have
   a space after your last line in your wp-config.php
 * for more details go to :**

   SOLUTION open wp-config.php in text editor. scroll down to last line and delete
   anything after the last ?>

 * Altoyes,
 * Thanks, that seems to be it. I know this is a stupid question; what do you mean
   by re-upload the wp-config.php?

 * Well if the problem is solved you wouldn’t need to do anything else. Suppose 
   altoyes was saying if you had to fix something in wp-config.php and did that 
   on your local machine you would need to reupload.
 * Just as a note, with something like FileZilla, you can edit the post on the host
   side by right click on the file and editing it, then make the change, exit and
   say yes to save, then tell filezilla to resave that changed file. Sounds more
   complicated than it really is…

 * Filezilla needs to have the filezilla setting of “file viewer/editor” set to 
   a plain text editor. (NOT Word. Something like Ultraedit, or equal.)

 * In my case it was a blank space between two PHP tags:
 * <?php
 * ?>
    (space here) <?php
 * ?>
