Cara menggunakan wordpress logs

From conflicts between WordPress plugins to poorly coded themes and mistakes in custom coding, several problems sound the alarm with website error codes and warnings. Even if you’re not sure what the warnings mean, you must fix them. The first step is learning how to set up a WordPress error log.

As a short explanation, a WordPress error log is exactly what it sounds like: a list of error codes and times that occur on your website.

In this post, we’ll show you how to set up and work with WordPress error logs using the built-in WordPress debug mode.

When should you set up a WordPress error log?

Consider setting up a WordPress error log in the following situations:

• When you see a blank screen while trying to load your website.
• When a warning with an error code (401, 404, 500, etc.) appears.
• If your entire site crashes.
• If you’re noticing slow website performance.
• If a plugin or theme isn’t working properly.
• If you’re curious as to which plugins or themes are causing performance issues.

As is often the case with WordPress, you have two routes to enable error logging with WordPress debug mode:

1. Manually
2. With a plugin

We’ll start by showing you the manual method, which just involves adding a few code snippets to your site’s wp-config.php file.

Then, if you want an even simpler option for error logging, we’ll share a free plugin that can get the job done.

Here’s how to do it manually…

Step 1: Access and edit the wp-config.php file

If you’re not familiar with your wp-config.php file, it’s one of the core files for holding important configuration details, like the credentials for your site’s database.

To access the wp-config.php file, either download and use an FTP client or a file manager tool in your host’s cPanel.

For this tutorial, we’ll cover the steps to access and edit your wp-config.php file with an FTP client.

In your FTP client, locate the wp-config.php file. This is normally in the root site directory.

Upon finding the file, right-click on it and select to edit or view the file. You’ll want to open the file in a text editor.

Step 2: Add a line of code in the wp-config.php file to turn on debug mode

Inside your text editor, search for a line of text that reads Stop editing! Happy blogging.

Place your cursor on the empty line above that line of text.

Paste in the following code:

define( 'WP_DEBUG', true );

If you already notice this line of code in the file, it may currently be set to false. If that’s the case, switch it to true.

Afterward, save the file to your computer and upload the wp-config.php file as an update to your website. This is done through the FTP client.

Great! Now debugging mode is activated for your WordPress site.

Step 3: But wait! I don’t want the errors to show on the frontend of my website

If you took a moment to check your dashboard or the frontend of your site, you may have already seen WordPress errors listed for everyone to see. This may not seem like a big deal if they show up on the WordPress dashboard, but you definitely don’t want the warnings on the frontend.

Not only is publicly displaying errors confusing for your visitors, but it can also be a security risk because it gives them detailed information about your site.

In short, debugging mode is messy when activated by itself.

Therefore, we need to log the errors in WordPress so they are recorded but not publicly displayed.

To log your errors, go back to that exact same wp-config.php file in the text editor.

Look at the debug code you recently pasted into the file. Paste the following new code on the empty line below the debug code:

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );

Again, in some situations you might discover that the debug log code is already included. For that, simply make sure that the false at the end of the code is changed to true.

The first line tells WordPress to save error messages to a file called debug.log. The second snippet tells WordPress not to publicly display error messages.

Now, your error messages will be safely saved in the log file, but neither you nor your visitors will have to see error messages while browsing your site.

For a second time, save the wp-config.php file in your file editor and upload it back to your WordPress website.

How to use a WordPress error log plugin

If you don’t feel comfortable working directly with your site’s configuration file, you can also use the free WP Debugging plugin:

As soon as you activate the plugin, it instantly activates WordPress debug mode and enables error logging. It also lets you control whether or not to display debug messages on your site by visiting Tools -> WP Debugging.

Checking your WordPress error logs

We’re assuming you already know the website pages that are alerting you of errors.

You must visit these pages now that the debugging log is configured and ready to store the errors.

Reconnect to your website files using the FTP client. You can also connect via your host’s cPanel.

Go to the /wp-content/ folder.

Open that folder and look for a file called debug.log.

This is the file you created from the previous steps.

What should I do with this debug log file?

The debug.log file is accessible by editing, viewing, or downloading the file. It’s similar to the previous steps, where you might either just preview the file to look at it or open it in a file editor to make changes and save it for later.

Overall, a debug log file is for reference, not for editing. Therefore, you have to sift through the list of errors and warnings to identify what’s wrong with your site, theme, plugins, or code.

For most people, the error log codes mean nothing. If anything, it’s closer to gibberish than English. However, you don’t want to forget about those errors.

Your resolution steps should go like this:

• You identify an error with the debug log.
• You find the error code.
• You look up what that error code means.
• You utilize a separate guide to fix that error.
