   time!

 * Hi,
 * I have been running a fairly recent version of wordpress for several months now
   without a glitch. Fantastic software! However I recently started getting the 
   following error when trying to add / modify a post.
 * I have checked the WordPress FAQ’s and the support forums for this problem and
   have tried everything that’s been suggested i.e. removing any whitespace (using
   Dreamweaver). I’m not able to find a specific support post for the page/s that
   seem to cause the problem. Any help would be much appreciated. Thanks in advance.

 * I got a similar problem logging in!
 * I just tried to install WordPress for the first time. My MySQL is not on localhost
   where the website runs, I hope this might explain something to the experts.
 * I get the same errormessage, several times. My first impression would be that
   it has to do with file protection.
 * Does anyone have an idea where to look?

 * In My case, the problem was caused by trailing space in the WP-config file. Make
   sure that it looks like:
 * ————-file wp-admin.php: first line just <?php
 * > <?php
   >  // ** MySQL settings ** // define(‘DB_NAME’, ‘mydb’); // The name of
   > the database define(‘DB_USER’, ‘dbuser’); // Your MySQL username define(‘DB_PASSWORD’,‘
   > dbpwd’); // …and password define(‘DB_HOST’, ‘myhost’); // 99% chance you won’t
   > need to change this value
   > // You can have multiple installations in one database if you give each a unique
   > prefix
   >  $table_prefix = ‘wp_’; // Only numbers, letters, and underscores please!
   > // Change this to localize WordPress. A corresponding MO file for the
   >  // chosen
   > language must be installed to wp-includes/languages. // For example, install
   > de.mo to wp-includes/languages and set WPLANG to ‘de’ // to enable German language
   > support. define (‘WPLANG’, ‘nl_NL’);
   > /* That’s all, stop editing! Happy blogging. */
   > define(‘ABSPATH’, dirname(__FILE__).’/’);
   >  require_once(ABSPATH.’wp-settings.
   > php’); ?>
 * ——————so not even a white space as trailing char.

 * Still no joy. Error message as follows:
 * –error message–
 * Warning: Cannot modify header information – headers already sent by (output started
   at /data/11/0/112/128/764617/user/782111/htdocs/site/en/wp-includes/wp-db.php:

   on line 122
 * –error message–
 * Checked files; wp-db.php and post.php and wp-config.php for trailing white space
   but it all looks clear to me?
 * Any other ideas!?
 * Thanks

 * I’m really sorry, I am just a novice user with no knowledge of PHP at all.
    Just
   downloaded wordpress 2.0.3, and it worked after the white space correction. Maybe
   it could help to choose an other template? I was quite happy with the greentrack
   template, modified it a little bit (translated it in dutch). You can get an impression
   of what is possible with WordPress for a complete novice user at [http://plutone.labarca.nl](http://plutone.labarca.nl)
 * grtz,
