stuck on test page after ubuntu update

Ampache WebUI remains stuck on test page with PHP errors and MySQL database connection issues

Description:
I am encountering an issue with the Ampache WebUI: the page remains stuck on the test page (see screenshot). This, I presume, occurred after an operating system update. Indeed, Ampache was functioning properly before this occurrence, and there were no changes made to the program's installation process.
Environment:
Ampache Version: 6.2.1
SQL: MariaDB (SQL)
Operating System: Linux 5.4.0-174-generic #193-Ubuntu
Browser: chrome, firefox

Thank you for your assistance in resolving this issue.

Looks like your version of PHP may have been upgraded. Make sure that php-intl and php-msql packages are installed. They may have been removed by the upgrade. sudo apt install php-intl php-mysql. Optional packages to install are php-curl php-xml and php-gd

all these packages, including optional ones, are already installed (i.e. php-intl is already at the latest version (2:8.3+94+ubuntu20.04.1+deb.sury.org+2) )

This is a long shot but in my case when PHP got updated the configuration files are not transferred to the new version of php.ini. You may have to manually update the configuration files.

Is Apache using the correct version of PHP? For example, I'm using php8.2-fpm.

a2query  -c php8.2-fpm
php8.2-fpm (enabled by site administrator)

a2query  -c php8.3-fpm
No conf matches php8.3-fpm

etc/apache2/conf-available# a2query  -c
serve-cgi-bin (enabled by maintainer script)
security (enabled by maintainer script)
httpd-proxy (enabled by site administrator)
localized-error-pages (enabled by maintainer script)
backuppc (enabled by maintainer script)
charset (enabled by maintainer script)
php8.2-fpm (enabled by site administrator)
apache2-doc (enabled by maintainer script)
phpmyadmin (enabled by maintainer script)
ttrss (enabled by site administrator)
other-vhosts-access-log (enabled by maintainer script)
javascript-common (enabled by maintainer script)


    <FilesMatch ".+\.ph(?:ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php8.2-fpm.sock|fcgi://localhost"
    </FilesMatch>

Thanks. You helped me to solve a lot.
I used
sudo apt install php8.3-fpm
to update,
then
sudo a2enconf php8.3-fpm
to enable the new apache configuration
and restarted apache
