Thanks. Purged php (all three versions) and Apache. Reinstalled and everything is working now.

Thanks. This is a new computer and all I have installed was Home Assistant and Dokuwiki. One of them may have installed PHP. Is PHP likely upward compatible? I.E. if PHP7 was installed by DokuWiki, is it likely to work fine with PHP8?

Thanks, this is how I installed Apache and PHP sudo apt install apache2 sudo apt install imagemagick php php-{fpm,intl,xml,curl,gd,mbstring,mysql,apcu,zip} Can I simply copy the mbstring.so and intl.so into the directory that php.ini says it's supposed to be in, or did I do something wrong with the install?

Well, you have just quadrupled my knowledge of PHP. My extension_dir is /usr/lib/php/20210902, but the extensions aren't there. I do find them, however in two other directories: /usr/lib/php/20160303/mbstring.so /usr/lib/php/20220829/mbstring.so /usr/lib/php/20160303/intl.so /usr/lib/php/20220829/intl.so Can I simply copy the files into the directory that php.ini says it's supposed to be in? After which, do I need to run sudo phpenmod mbstring intl as suggested by kicken?

Thanks. Your assistance is appreciated. Easy to do, but which php.ini file? /etc/php/8.1/apache2/php.ini /etc/php/8.1/cli/php.ini I edited both php.ini files and rebooted the server, but the problem persists. Just to be certain I installed them with: sudo apt update sudo apt install php-mbstring sudo apt install php-intl What did I miss?

I installed Ubuntu 24.04 Desktop on a miniPC, I installed Apache2 I installed PHP8 I installed MediaWiki Then I got this error on my first logon to MediaWiki: What I know bout PHP could fit on a postage stamp. I installed the missing extensions (mbstring and intl) using sudo apt install. Now, how do I get PHP to recognize the plugins?
