The issue is caused by an undefined variable in your PHP code. Here’s how to fix it.
Initialize Variables: Ensure variables are defined before use. Modify the PHP code to check if a variable is set:
$variable = isset($variable) ? $variable : 'default_value';
Check Theme or Plugin Code: Go to the specific theme or plugin file causing the issue (often in functions.php or a custom template) and make sure all variables are initialized properly.
Enable Debugging: To log errors and pinpoint the exact issue, add this to wp-config.php:
define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); @ini_set( 'display_errors', 0 );
Update Plugins/Themes: Ensure your theme and plugins are updated to avoid compatibility issues.
