 * The first line of your wp-config.php file contains something other than `<?php`.
 * wp-config.php can *not* have anything outside of the <?php and ?> markers. This
   includes blank lines, spaces, anything. The very first characters must be <?php
   and the very last ones must be ?>. Nothing else will work.

 * There can’t be any space after the closing ?> either, so check that as well.

 * this is the content of my wp-config.php
 * <?php
    define(‘DB_NAME’, ‘lensakre_lensakreatifDB’); // The name of the database
   define(‘DB_USER’, ‘deleted’); // Your MySQL username define(‘DB_PASSWORD’, ‘deleted’);//…
   and password define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to 
   change this value define(‘DB_CHARSET’, ‘utf8’); define(‘DB_COLLATE’, ”);
 * // You can have multiple installations in one database if you give each a unique
   prefix
    $table_prefix = ‘lensakre_’; // Only numbers, letters, and underscores
   please!
 * // Change this to localize WordPress. A corresponding MO file for the
    // chosen
   language must be installed to wp-content/languages. // For example, install de.
   mo to wp-content/languages and set WPLANG to ‘de’ // to enable German language
   support. define (‘WPLANG’, ”);
 * /* That’s all, stop editing! Happy blogging. */
    define(‘ABSPATH’, dirname(__FILE__).’/’);
   require_once(ABSPATH.’wp-settings.php’); ?>

 * It’s irrelevant what the content of you wp-config file is. Open your wp-config
   file in notepad or some other simple text editor, if you open it in Word then
   shame on you. Then place your cursor just in front of the <?php and backspace
   like it’s going out of style. Then save the file and reupload the file.

 * awangr: I really wasn’t asking you what the content of wp-config.php was, I was
   actually telling you what it was.
 * Before the <?php, you have something else. It might be a blank line. It might
   be a space. I don’t know. But it’s there. Your error message tells me so:
 * > _(output started at /home/lensakre/public\_html/wp-config.php:1)_
 * That says that line one of wp-config.php is producing output. There’s one way
   it can do that.
 * If this is a new installation, then perhaps you edited the wp-config.php file
   with something that is not a text editor. Start with a fresh copy and use a normal
   text editor. Notepad will do. Word will not.

 * hi otto42, thanks
 * i edited it with notepad (even used scriptol-php) trying to remove something 
   in front of the <?php, but it still give me the same error message.

 * When you upload the files to your server do you use ftp if so do you also make
   sure to use ASCII mode instead of binary.

 * awangr:
    Redownload a fresh copy of WordPress. Make a copy of the wp-config-sample.
   php file. Edit that file using Notepad and put your database parameters in. Use
   this new file.
 * Once a file has been badly edited with a bad editor, fixing it is difficult. 
   Starting from scratch is easier.

 * hi all,

 * that’s a Firefox problem as it’s happened to me. Something to do with the plist
   file for Firefox I think.

 * For what it’s worth, I uploaded the zipped WordPress 2.3 distro and unzipped 
   it on my server, then did my install, and also ran into the same problem awangr
   did. After reading this thread, I looked at my config file and found two returns
   at the end of the config file. Removing the two returns solved the problem. (
   I *also* had the cookies problem, but two forced reloads in both Safari and Firefox
   after the removal of the returns got around that.)
