Troubleshoot

Wordpress plugin install: Could not create directory

sudo chown -R www-data:www-data ../../wordpress_webdevzine/

Change password

UPDATE `wp_users` SET `user_pass` = MD5( 'new_password' ) WHERE `wp_users`.`user_login` = "admin_username";

wp-json/elementor/v1/globals 404 not found

Restarting a couple of times worked...

Going into settings->permalinks and re-saving the setting, worked.

Turn on logging

@ini_set( 'display_errors', getenv('display_errors') );
@ini_set( 'display_errors', 1 );

/var/www/html/wp-content/debug.log will have the file.
