Fixing Pluggable.php File Errors in WordPress

The pluggable.php file is a core WordPress file. It’s never a good idea to edit the core WordPress file as your first option, even when there is an error pointing to them.

Most likely than not, the error is coming from a different location.

In order to fix any error mentioning pluggable.php file, just look at the first location mentioned in the error.

Warning: Cannot modify header information – headers already sent by (output started at /home/username/demosite/wp-content/themes/mytheme/functions.php:1035) in /home/username/demosite/wp-includes/pluggable.php on line 1179

In the above example, the error is located in the theme’s functions.php file at line 1035.

This means you need to edit your theme’s functions.php file and change or remove the code causing this error.

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.

Let’s take a look at another example:

Warning: Cannot modify header information – headers already sent by (output started at /home/username/demosite/wp-content/some-plugin-name/some-plugin.php:144) in /home/username/demosite/wp-includes/pluggable.php on line 1090

This error message is pointing to a plugin on your WordPress site causing the error. You can simply deactivate the plugin and notify the plugin author about the error.

In almost all cases, errors mentioning pluggable.php file are not caused by the file itself.

These errors are usually caused by a custom code snippet you added to functions.php file, or a poorly coded plugin, or even your WordPress theme.

Simply removing or editing the code or deactivating the plugin will make the error go away.
