If we talk about the WordPress error log, then it has great importance for a WordPress website. When you apply an error log inside the wp-config.php file, you can trace the error and solve it accordingly. The steps of applying code are simple.
Login to the FTP account to access the WordPress file from the main server. You can also get the access of the server files through CPanel admin
Find the root directory on the server
Now search the wp-config.php file into the root folder
Edit the wp-config.php file and search the line that says "happy blogging."
Now write two codes before the line
define( 'WP_DEBUG', true );
define('WP_DEBUG_LOG', true );
After placing these codes, you can assure yourself that in the future, you can check the error log for any error. Moreover, the codes are also working as a debugging tool for the website. It means that if you face errors such as internal server error, white screen of death error, parse error, 403 forbidden error on the website, then you can check the error log and plan your troubleshooting process.
The internal server error or 500 internal server erroris one of the most found errors on the website. Solve this error by applying the following ways
Refresh your web page, because sometimes error is temporary and refreshing browser can work often
Clear cookies and cache of the website, because they can also bring internal server error for the website
