Lỗi này thường thấy nếu ta dùng PHP 7 và vì PHP 7 không còn hỗ trợ hàm mysql_connect() nữa, thay vào đó nó có hàm mysqli_connect(). Thể hiện của lỗi này như sau:
This page isn’t working www.kindalog.com is currently unable to handle this request. HTTP ERROR 500
Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /wp-includes/wp-db.php:1665 Stack trace: #0 /wp-includes/wp-db.php(632): wpdb->db_connect() #1 /wp-includes/load.php(425): wpdb->__construct('u', 'p', 'd', 'h') #2 /wp-settings.php(116): require_wp_db() #3 /wp-config.php(93): require_once('/home/kindalog') #4 /wp-load.php(37): require_once('/home/kindalog') #5 /wp-blog-header.php(13): require_once('/home/kindalog') #6 /index.php(17): require('/home/kindalog') #7 {main} thrown in ~/wp-includes/wp-db.php on line 1665

Để khắc phục lỗi này, ta xóa hoặc gán giá trị false cho WP_USE_EXT_MYSQL trong file wp-config.php.
define( 'WP_USE_EXT_MYSQL', false );
Tiếp theo, mở trang quản lý PHP version trên web server và chọn mysqli.
Thanks for sharing your thoughts on website. Regards
You have made some good points there. I looked on the web for more information about the issue and found most people will go along with your views on this web site. Anthea Mickey Almeria
Hey there 🙂
Your wordpress site is very sleek – hope you don’t mind me asking what theme
you’re using? (and don’t mind if I steal it? :P)
I just launched my site –also built in wordpress like yours– but the
theme slows (!) the site down quite a bit.
In case you have a minute, you can find it by searching for
“royal cbd” on Google (would appreciate any feedback) – it’s still in the works.
Keep up the good work– and hope you all take care of yourself during the coronavirus scare!
