   Hi, Thanks for the insight. I had a similar error preventing me from logging into my admin area. The page was just blank.

   Warning: Cannot modify header information

   I followed your instruction on case one, removing a space after the PHP closing tag and it worked out for me

    I can’t log in to my admin page at all. I know exactly how to fix it, but I can’t log in. How can I access my page if it won’t let me log in through the WordPress login page?

      It would depend on the error, for some workarounds when you’re unable to log in you can take a look at our article here: https://www.wpbeginner.com/beginners-guide/beginners-guide-to-troubleshooting-wordpress-errors-step-by-step/

    This article is super helpful and actually resolved the error on my wordpress install. It was additional space in functions.php.

    Thanks a lot team. Keep up the great work.

    Thanks for the help!

    It was an extra space at the end of plugin.

    This step worked for me..
    “Sometimes the headers already sent error is caused by an extra space after closing the php ?> tag, so you can just remove that, and it will fix the issue.”

    Hi, I see a message like that. I was trying to update my theme when the message appeared. The problem is that the message blocks the access to my dashboard. I mean, it doesn’t even allow me to log in to my dashboard anymore!!! what can I do? this is the message: Warning: Cannot modify header information – headers already sent by (output started at /home3/angelasobral/public_html/wp-content/themes/glowline/inc/static-function.php:238) in /home3/angelasobral/public_html/wp-includes/pluggable.php on line 1210

    Thank you very much for the really helpful article. I faced an error occuring in my website because of the Comment Code just after PHP start tag <?php
    something like this…

    /*
    Plugin Name: Some Name
    Plugin URI:
    Description: Some Description
    Author: Author Name
    Author URI:
    Version: 2.1
    */

    I removed comment part and it solved my problem.

    Thanks a lot for the help.

    Developing a plugin, and added the wp_safe_redirect call to the plugin. Getting an ‘function wp_safe_redirect’ not found error.

    I think this is because pluggable.php is not loaded until *after* the plugin. Is this correct, and how do I fix it?

    This error is killing me! I deactivated the plugins and it is got the site up but I can’t access the admin area. Getting this:

    Warning: Cannot modify header information – headers already sent by (output started at /home/content/f/i/n/finmadden/html/wp-includes/class-walker-page.php:1) in /home/content/f/i/n/finmadden/html/wp-includes/pluggable.php on line 1179

    any thoughts?
