To enable error logs you will have to add the following line to file:

php_flag log_errors on

Then we will have to determine a location for the logs to be stored. For our example we created the error_log.txt file on public_html directory. For logs to be stored in the file created, insert the following line into . htaccess:

php_value error_log /home/usuario_FTP/public_html/error_log.txt
