You may get an error 500 or a blank page when you open your WordPress website. To find out which plugin or broken code is causing that error you need to tell WordPress to write errors into a log file or to show them on the screen instead of showing just the white blank page.
You can enable the WordPress debug mode by editing a few lines in the wp-config.php file of your WordPress installation.
To enable debugging mode in WordPress, follow the steps:
- Login to cPanel or log in to your site via FTP
- Use the cPanel File Manager or your FTP client to edit the file
- Add the lines below to the
wp-config.phpor if they already exist just change their values:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
Attention: Make sure that you write the lines exactly as shown.
Do not forget any semicolon or other characters!
After reloading the website all WordPress debug errors will be written into the file debug.log which is located in the folder:
If you want to see the debug log errors directly on the screen instead of having the need to look into the debug.log change
define( 'WP_DEBUG_DISPLAY', true );
When we ask you to do so please send us the debug.log file.

WordPress Debug Log is not Created
Some hosting providers do not create the WordPress debug.log at all. They catch all errors and warnings which are created by WordPress and write them into a separate log file. So if the debug.log is not created check if there is another file in the root of your website like
error_log or a folder like
If you do not see any error logs at all please ask your hosting provider where they store the log files.
Alternatively, you can try to set in the wp-config.php
define( 'WP_DEBUG_DISPLAY', true);
If this works you will see the relevant errors on the front end. This will help you to resolve the fatal error which you get, but this should also be used only in the last instance because your visitors should not be faced with such error messages for security purposes. So when you do not need it any longer make sure to switch the value back to false.

Change the location of the debug.log
You can change the location of written errors by changing the value of the constant WP_DEBUG_LOG from
true to a path of your choice like so:
define('WP_DEBUG_LOG', ABSPATH . '/logs/errors.log');
This allows you to write errors into another file located elsewhere and even allows you to write errors to
This can be helpful if you use docker or another development environment and want to have all your logs into one location.
