Error logs are your first line of defense when something goes wrong on your WordPress site. They provide detailed information about what caused an issue, such as:
Plugin or theme conflicts
PHP errors
Database connection problems
Server-related issues
Without error logs, diagnosing problems can feel like searching for a needle in a haystack. By enabling and reviewing error logs, you can pinpoint the root cause of issues and fix them efficiently.

1. Enable Debugging in WordPress:
WordPress has a built-in debugging feature that logs error to a file. To enable it:

Access Your wp-config.php File: Use FTP, your hosting file manager, or SSH to locate the wp-config.php file in the root directory of your WordPress installation.

Enable Debugging: Open the file and look for the line:

define('WP_DEBUG', false);

Replace it with:

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

WP_DEBUG: Turns on debugging mode.
WP_DEBUG_LOG: Saves errors to a log file (wp-content/debug.log).
WP_DEBUG_DISPLAY: Prevents error from being shown to visitors.

Save the Changes: Save the wp-config.php file and upload it back to your server if necessary.

2. Locate the Debug Log File: Once debugging is enabled, WordPress will start logging errors to a file called debug.log in the wp-content directory.
