Greetings all: We are at the tail end of numerous system upgrades to our LAMP server, including moving from ubuntu 16.04 --> 19.10 -- > 20.04, and PHP from 7.0 to 7.4. We run a vhost config, including email services. All systems are running normally, except for php (under apache, not cli): PHP CLI: Code: [email protected]:/etc/php$ php -v PHP 7.4.7 (cli) (built: Jun 12 2020 07:44:21) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies MySQL: Yet no matter we tweak, poke and prod, apache is still trying to pull the wrong version (7.0, which was the last actively used version), so things go pear-shaped from there. Currently, any of our hosted sites that don't use a db work fine, but those that do, appropriately get the same error: Code: Uncaught Error: Call to undefined function mysqli_connect() (the path identified as /etc/php/7.0... does not exist) Only 7.3 and 7.4 are installed on the system; 7.3 is disabled, and 7.4 is enabled, based on apache mods-availabe and sites-available configs. We're hoping someone out there has our 'duh' moment, but we're just not seeing it. As always, any help or directly would be much appreciated.
