error in wp-db.php and pluggable.php

Maybe it’s because error_log() function is disabled by your server administrator. Not all server faces this problem.

And I think it’s a bug in 2.3.2. WordPress should check whether the function is enabled by the server or not before calling it. Try commenting the error_log() call on wp-db.php line 163 until future fixes.

e.g.:
/* error_log($error_str, 0); */

re: host http://www.zymic.com

Confirming this change (commenting out line 163 in /wp-includes/wp-db.php at 2.3.2) fixed the problem when using host http://www.zymic.com and allowed installation of WordPress to complete successfully.

This change had no effect for me regarding this error. I did find extra lines beneath the final ?> in my functions.php. Removal of these corrected the problem.

The same problem on 1 hosting on half of my WordPress 2.3.2 blogs:

Warning: Cannot modify header information – headers already sent by (output started at /home/ga/public_html/wp-settings.php:266) in /home/ga/public_html/wp-includes/pluggable.php on line 341

Warning: Cannot modify header information – headers already sent by (output started at /home/gasyoun/public_html/esiod.com/wp-content/themes/illacrimo/functions.php:24) in /home/ga/public_html/ga/wp-includes/pluggable.php on line 391

The resolution (comment out line 163 in wp-includes/wp-db.php at 2.3.2) worked on a http://www.plus.net hosted account. Interestingly, just an internal server error message was displayed before the fix was applied.

None of the fixes above seemed to work for me, even after upgrading to the latest version of WordPress. The actual blog works fine, but then when I try to login I get this error…

Warning: Cannot modify header information – headers already sent by (output started at /home/trideade/public_html/blog/wp-config.php:25) in /home/trideade/public_html/blog/wp-login.php on line 12

Warning: Cannot modify header information – headers already sent by (output started at /home/trideade/public_html/blog/wp-config.php:25) in /home/trideade/public_html/blog/wp-login.php on line 24

Can someone help me out please?

remove the line breaks OR spaces that are after the closing ?> inside your wp-config.php

That worked! I was getting “Headers already sent” on wp-config was well and all I did was delete the extra spacing, lines after the ?> on wp-config.php. Thanks whooami
