Support » Fixing WordPress » Database / Header / Error / Help Please!

  • Sorry this a re-post as I had no replies before. I’m hopig someone can help this time!


    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

    // ** 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 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__).’/’);

    ——————so not even a white space as trailing char.

    Thanks I’ll check that out and let you know how I get on!

    Still no joy. Error message as follows:

    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!?


    strange – above just seems to happen with one particular post?

    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).
