When and Why You See Pluggable.php Errors?
WordPress allows users and plugins to override certain core functions. These functions are located within the pluggable.php file.
If a WordPress plugin or a custom code snippet fails to properly handle one among these functions, then you’ll see a mistake like this one:
Warning: Cannot modify header information – headers already sent by (output started at /home/username/demo site/wp-content/themes/mytheme/functions.php:1035) in /home/username/demosite/wp-includes/pluggable.php on line 1179
Sometimes you’ll be ready to continue performing on your site with this or another error still appearing within the admin area.
Having said that, let’s take a glance at the way to easily fix the pluggable.php file errors in WordPress.
Fixing Pluggable.php File Errors in WordPress
The pluggable.php file may be a core WordPress file. It’s never an honest idea to edit the core WordPress file as your first option, even when there’s a mistake pointing to them. Most likely than not, the error is coming from a special location.
In order to repair any error mentioning the pluggable.php file, just check out the primary location mentioned within the error.
Warning: Cannot modify header information – headers already sent by (output started at /home/username/demo site/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 found within the theme’s functions.php file at line 1035.
This means you would like to edit your theme’s functions.php file and alter or remove the code causing this error.
Sometimes the headers already sent error is caused by an additional space after closing the PHP ?> tag, so you’ll just remove that, and it’ll fix the difficulty.
Let’s take a look at another example:
Warning: Cannot modify header information – headers already sent by (output started at /home/username/demo site/wp-content/plugins/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’ll simply deactivate the plugin and notify the plugin author about the error. In most cases, errors mentioning the pluggable.php files aren’t caused by the file itself.
These errors are usually caused by a custom code snippet you added to the functions.php file, or a poorly coded plugin, or maybe your WordPress theme. Simply removing or editing the code or deactivating the plugin will make the error getaway.
