Kemarin saya saya coba update package di virtualmin dan setelah nya wordpress saya muncul error ” your php installation appears to be missing the mysql extension which is required by wordpress. “

ternyata setelah saya coba perhatikan dia melakukan update php nya, virutalmin saya di install di ubuntu 16 dengan php 5.6 dan dia melakukan update dan upgrade ke versi php 7.03 dan php 7.4.12 , dan ternyata ketika melakukan upgarde php akan menghapus ekstensi php-mysql , bisa kita cek dengan membuat file info.php di folder public_html situs kita kemudian isi dengan script php info

<?php
phpinfo( );
?>

save kemudian akses url nya https://aldy.alshifacharity.com/info.php ctrl+f ketik mysql , jika memang ada ekstensi mysql nya dia akan ada di section mysql dan ada client API version nya

nah jika tidak ada bisa coba kita install lagi php-mysql nya
