Why and When You Should Turn Off PHP Errors in WordPress?

PHP errors that you can see on your WordPress site are usually warnings and notices. These are not like internal server error, syntax errors, or fatal errors, which stop your website from loading.

Notices and warnings are the kind of errors that do not stop WordPress from loading your website. See how WordPress actually works behind the scenes for more details.

The purpose of these errors are to help developers debug issues with their code. Plugin and theme developers need this information to check for compatibility and best practices.

However, if you are not developing a theme, plugin, or a custom website, then these errors should be hidden. Because if they appear on the front-end of your website to all your visitors, it looks extremely unprofessional.

If you see an error like above on on your site, then you may want to inform the respective theme or plugin developer. They may release a fix that would make the error go away. Meanwhile, you can also turn these errors off.

Let’s take a look at how to easily turn off PHP errors, notices, and warnings in WordPress.

Turning off PHP Errors in WordPress

For this part, you will need to edit the wp-config.php file.

Inside your wp-config.php file, look for the following line:

define('WP_DEBUG', true);

It is also possible, that this line is already set to false. In that case, you’ll see the following code:

define('WP_DEBUG', false);

In either case, you need to replace this line with the following code:

ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

Don’t forget to save your changes and upload your wp-config.php file back to the server.

You can now visit your website to confirm that the PHP errors, notices, and warnings have disappeared from your website.

Turning on PHP Errors in WordPress

If you are working on a website on local server or staging area, then you may want to turn on error reporting. In that case you need to edit your wp-config.php file and replace the code you added earlier with the following code:

define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', true);

This code will allow WordPress to start displaying PHP errors, warnings, and notices again.

  1. Thank you so much! This fixed my problem in 30 seconds that I have been waiting for my hosting to fix for over 12 hours.

    • Glad our guide could help. As a reminder, this hides the error from your site but you would want to try to resolve the root cause of the error you were seeing.

  2. I have already done false in all . But in healthsite status always show WP debugging mode is enabled. please suggest me something

    • You likely have it set to true in another section of the code, you likely want to reach out to your hosting provider for them to take a look and assist you.

    • You would want to ensure wp_debug isn’t already added in your file somewhere else.

      Admin

    • You may want to check with your hosting provider to see if they have a log set up from their end

  3. I’ve been advised to turn these notices off and was directed to this article to help me with that. However, I do not have the ‘wp_debug’ line in my config file. Do I just add it in? And if so whereabouts in the file?
    Thanks!

    • You may want to ensure you did not miss it in your current file but, you would place the code at the bottom of the file :)

  4. Clueless newbie! I’ve changed the wp-config.php file and saved it .. Do I have to upload this file to the server to get it to work? How do I do that Using Cpanel File manager.. Not seeing any debug suppression so I guess its somehow not picking up the edited file.. Halp Halp!

    Thanks,

    GG

    • If you’re using the file manager your host offers, and directly edited and saved through that without downloading the file then the changes should be active on your site and you would want to check with your host for why the changes may not be getting applied to the file.

  5. ok so i know this is old, but i’m stumped. i am still getting php errors.

    Fatal error: Uncaught Error: Call to undefined function get_header() in /path/to/wordpress/wp-content/themes/mytheme/index.php:5 Stack trace: #0 {main} thrown in /path/to/wordpress/wp-content/themes/mytheme/index.php on line 5

    note that this issue was caught by a pen test and i was asked to suppress the error to avoid full paths being reveled. Any ideas would be helpful

    • That is a fatal error for why it is still being displayed, you would want to either change themes or let your theme’s support know about the error to let you know how to fix it.

  7. I faced the same problem after upating woocommerce plugin and the I used your method
