Headers already sent warning problem

Possibly an error/warning being output on /wp-includes/pluggable.php on line 881

You can try and trap the output using this code

<?php//you probably don't need to open PHP tags

ob_start();//place this before line 881

//line 881 content (or other suspect content)

//then capture the output soon after the suspect content
$error_out=ob_get_clean();

//mail it to yourself to see what it says.
mail('your@emailaddress.com','error output','-'.$error_out.'-');
//If mail is empty look for white space between the dashes.

//probably don't need to close either
?>

This will possibly fix the issue as it traps the output an prevents it being output before the headers are sent. However mail it to yourself and see if it’s something you can fix. If it moves the error line number repeat until you see what the problem is.

This error is fatal and killing hte script before you get to use javascript.

You say you’ve cleaned the blank spaces but it’s possible you haven’t. I’ve seen weird bugs and sometimes it’s easiest to start again. Try making a new config file. Transfer the config info to the example, re-save as wp-config.php and FTP it to your WordPress folder.
