Wordpress Warning: Cannot modify header information...

Hi,

I am trying to install Wordpress in my language, Turkish. I uploaded all the files, created the database and when I check

http://www.thewebsite.com/wp-admin/install.php 

Code (markup):

it gives the following warning message.

Warning: Cannot modify header information - headers already sent by (output started at /home/xxx/public_html/thewebsite.com/wp-config.php:1) in /home/xxx/public_html/thewebsite.com/wp-admin/install.php on line 36

Code (markup):

I searched the net and did what some people suggested but it did not solve my problem. I know the problem is in wp-config.php file line 1, but can't see what it is.

The file is below:

<?php
/**

 * Secret Keys, WordPress Language, and ABSPATH. You can find more information by

Can somebody please help?

 

Download fresh bunch of files from wordpress.org and install with them.
looks like config.php file having some error, Not sure though! Give it a try.

 

Already tried it, didn't work.

 

try installing Wp on English version, and add your language to wp-content/languages/.

 

rename config.php file to something else and see if that works.

 

check for white spaces before <?php or after ?> in wp-config.php and install.php

 

Are you trying to reinstall?

wp-config.php file is generated on completion of the installation process so I assume you have already tried to perform that task once. What you can do is completely remove wp-config.php file from the server and make sure there is a wp-config-sample.php file there instead. Also check the database and drop any WP related tables (prefixed with wp_ unless you've chosed a different table prefix) that might have been created during an incomplete install attempt.

Then restart the installation process and it should work fine.

Note: I also see your wp-config.php file is missing the closing php tag (?>). Add it there before doing anything else, just in case it makes a difference. Older PHP versions may have a problem with that as well.

 

Ok, the problem is solved when I opened the wp-config.php file within cpanel edit screen and deleted the empty spaces before <?php on the first row, that was not visible or deletable with notepad as I tried it before.

 

Good to hear that, ademedia. Try to avoid editing files through the wp-admin console in the future, always do that on your local computer and then upload to the live server. There's a good reason behind this method.
