The Pluggable.php error is one of the more puzzling errors you may encounter in WordPress.

Most commonly, this happens when you open a theme or plugin, but you may also encounter pluggable.php errors whenever you try to add a code snippet.

Basically, the reason why the pluggable.php is wrong is that the new function may not be able to override the default WordPress function.

pluggable.php is one of WordPress’ core files, which means that there is other content (most likely plugins or code snippets) that conflict with the natural behavior of this file.

Manually troubleshoot Pluggable.php file errors

The pluggable.php file is a core WordPress file. When you have an error pointing to a WordPress core file, it is never a good idea to edit it in the first place.

The error most likely came from a different location.

To fix any pluggable.php file errors, look for the first reference to it in the error message.

In the above example, the error can be found in the theme’s functions.php file, line 103. Not in the pluggable.php file.

Your theme’s functions.php file needs to be edited and the code causing this error needs to be replaced or removed.

The extra space after the php ?> tag can cause the headers sent error. So just remove the extra space and in most cases the error will go away.

Note that this error can also come from plugins that conflict with the pluggable.php file.

Summary

The pluggable.php error perfectly illustrates that you should try to install as few plugins as possible on your website.

Most plugins and themes available in the WordPress directory are of course safe and will not break your website.

However, every time you insert new content on your website, you increase the number of PHP requests your server has to handle.

This can increase your page load times and open security holes in your website.

The best way to identify plugins that are spamming your site is to monitor them with a solution like WP Umbrella.
