In Magento, you can enable debug mode and debug profiling by editing the “app/etc/env.php” file. Here are the steps to enable debug mode and debug profiling:
Log in to your server and navigate to the Magento root directory.
Open the “app/etc/env.php” file in a text editor.
Find the following line in the file:
‘MAGE_MODE’ => ‘production’,
Change ‘production’ to ‘developer’ to enable debug mode.
Find the following line in the file:
‘debug’ => array(
‘profiler’ => false,
),
Change ‘false’ to ‘true’ to enable debug profiling.
Save the file and exit the text editor.
Clear the cache by going to “System” > “Cache Management” and select “Flush Magento Cache” and “Flush Cache Storage”
Go to the frontend of your store and check if the debug mode and debug profiling are enabled.
Note: Enabling the debug mode and debug profiling can slow down your website and expose sensitive information, so it’s recommended to only use them in a development environment. You should disable them in a production environment.
It’s always good to take a backup of your database before making any changes and test the changes on a test environment before applying it to the live website.
