I have added correctly this code to the wp-config.php file:
define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false);
But can see debug.log file.
Also, I can't upload images in the library. I check the folder permission and it is set to 755. When I change to 777 it works. But I don't want to have 777. It's too risky.
Support Access enabled.
p.s. I also deleted my admin user but I do not know if it has a relationship with this issues.
