I am working in a WordPress site in Linux Mint. My file and folder permission is like below

I used below code in wp-config.php file

define( 'WP_DEBUG', true );

define( 'WP_DEBUG_LOG', true );

define( 'WP_DEBUG_DISPLAY', true );

@ini_set( 'display_errors', 1 );

But I am getting blank white page in WordPress Home page.

I checked wp-content folder for debug.log, but there is no debug.log file. I checked apache 2 error.log file, but it is empty.

What is the solution ?
