Upgraded a WordPress site to v4.5 and started getting the following warning:
PHP Warning: mysqli_real_connect(): Headers and client library minor version mismatch. Headers:100023 Library:100113 in /home/user/public_html/wp-includes/wp-db.php on line 1489
LiteSpeed latest and CloudLinux 6 no CPanel server. The website is using PHP v7 from AltPHP and MariaDB on a remote DB server. The DB server has CPanel but not CloudLinux.
I ran /usr/bin/alt-php-mysql-reconfigure checking the config before and after (ls -la /opt/alt/php*/usr/lib*/php/modules/mysql*.so). Output is the same both times.
