    If necessary, read a little more here.

    I read the Answers Trouble Shooting about this problem, but i don’t get it. I deleted <?php and ?> and reworte it, and there aren’t any spaces… :/

    Now i’ve eddited the wp-config.php 1000 times and deleted all spaces,

    1. Place the cursor between the ? and >
    2. Now press the DELETE key on your computer
    3. Keep that key pressed
    4. For at least 15 seconds
    5. Now type > and
    6. save without pressing any other key at all.
    7. If you press another key, you will bring the problem back.

    in this way, it doesn’t work. I added nothing to config.php, i downloaded wp-config-sample again and did it again and again :/

    Hm, it’s the most likely problem. What if you take the wp-config sample from the WP download, insert the right information (again), save as wp-config and reupload?

    Otherwise, I can only suggest to read some other ‘cannot modify header information’ treads to see if it could be something else…

    i downloaded wp-config-sample again and did it again and again :/

    u see, i tried it.

    I used the Windows “Editor” und “Dreamweaver”, both doesn’t work.

    You must use a simple text editor like Notepad or clone.
    Also, have you disabled all of your plugins?

    its not a plugin issue. the error you pasted is caused by characters or line breaks or spaces before the opening <?php in your wp-config.pgp

    I’ve downloaded Notepad and did it again and again, doesn’t work!

    Hier is the full code:

    <?php
    //** MySQL-Einstellungen **//
    define('DB_NAME', 'XXX');    // Der Name der Datenbank
    define('DB_USER', 'XXX');     // Ihr MySQL-Benutzername
    define('DB_PASSWORD', 'XXX'); // Sowie das MySQL-Passwort
    define('DB_HOST', 'localhost');    // Diesen Parameter müssen Sie in den allermeisten Fällen nicht ändern
    define('DB_CHARSET', 'utf8');
    define('DB_COLLATE', '');
    
    // Wenn Sie mehrere WordPress-Installationen in einer Datenbank haben,
    // muss jede Installation ein eigenes "Tabellenpräfix" bekommen
    $table_prefix  = 'wp_';   // Bitte nur Zahlen, Buchstaben und/oder Unterstriche
    
    // Setzen Sie für AUTH_KEY, SECURE_AUTH_KEY und LOGGED_IN_KEY ein Passwort oder
    // einen langen Satz ein. Sie werden ihn später nicht mehr benötigen, daher
    // machen Sie ihn ruhig lang und kompliziert. Unter http://api.wordpress.org/secret-key/1.0/
    // können Sie einen langen Passwortsatz automatisch generieren lassen.
    define('AUTH_KEY', 'Fuegen Sie hier einen beliebigen Satz ein.');
    define('SECURE_AUTH_KEY', 'Fuegen Sie hier einen beliebigen Satz ein.');
    define('LOGGED_IN_KEY', 'Fuegen Sie hier einen beliebigen Satz ein.');
    
    // Ändern Sie den folgenden Parameter, wenn Sie eine übersetzte Version von
    // WordPress nutzen. Für die gewünschte Sprache muss eine MO-Datei in
    // wp-content/languages liegen.
    // Installieren Sie beispielsweise de_DE.mo in wp-content/languages und
    // setzen Sie WPLANG auf 'de_DE', um WordPress auf deutsch zu haben.
    define ('WPLANG', 'de_DE');
    
    /* Ab hier sind keine weiteren Änderungen notwendig. Viel Spaß beim Bloggen! */
    
    define('ABSPATH', dirname(__FILE__).'/');
    require_once(ABSPATH.'wp-settings.php');
    ?>

    what you paste here doesnt show anything — since you wont see it in a copy and paste. If you have shell access you can see the problem by performing a cat on the file.

    This has been covered time and time and time again..

    Warning: Cannot modify header information - headers already sent by (output started at /var/www/web521/html/trashpage/wp-config.php:1)

    I read about 100 of these threads…

    Now it works.. i can’t believe it. I downloaded the original wp-config-sample and eddited it again with all programms, and it worked with some shit, called “the coder maker” from italy….

    Thank you guys!
