Apache2 configuration. Different PHP versions

I have a big problem with MyBB. I uploaded the files fine, gave rights 777.

000-default.conf entry from apache2:

<VirtualHost *:80>
    ServerName 192.168.1.19
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/web/

    <Directory /var/www/web>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    <FilesMatch \.php$>
        SetHandler "proxy:unix:/run/php/php8.2-fpm.sock|fcgi://localhost/"
    </FilesMatch>

    ErrorLog ${APACHE_LOG_DIR}/web_error.log
    CustomLog ${APACHE_LOG_DIR}/web_access.log combined
</VirtualHost>

<VirtualHost *:80>
    ServerName 192.168.1.19

    <Directory /var/www/mybb>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    <FilesMatch \.php$>
        SetHandler "proxy:unix:/run/php/php8.1-fpm.sock|fcgi://localhost/"
    </FilesMatch>

    ErrorLog ${APACHE_LOG_DIR}/mybb_error.log
    CustomLog ${APACHE_LOG_DIR}/mybb_access.log combined

    Alias /mybb /var/www/mybb

</VirtualHost>
<VirtualHost *:80>

        Options FollowSymLinks
        DirectoryIndex index.php
        AllowOverride All
    </Directory>

    <FilesMatch \.php$>
        SetHandler "proxy:unix:/run/php/php8.2-fpm.sock|fcgi://localhost/"
    </FilesMatch>

    ErrorLog ${APACHE_LOG_DIR}/phpmyadmin_error.log
    CustomLog ${APACHE_LOG_DIR}/phpmyadmin_access.log combined

    Alias /phpmyadmin /usr/share/phpmyadmin
</VirtualHost>

After typing 192.168.1.19/mybb does not work, same if I type 192.168.1.19/mybb/install or 192.168.1.19/install

MyBB must be using version 8.1. How to fix this? I have no strength left. ChatGPT can't help, I don't know anything about it. I am using Ubuntu 22.04.2 LTS. Apache version is 2.4.56, mariadb version is 10.11.2, php version is 8.1.17 (All packages from the stable release)

/var/ww/web and phpmyadmin must use php 8.2. The site and phpmyadmin work, but mybb does not.

You've configured several vhosts with the same ServerName 192.168.1.19 on the same port (80). Since the last vhos takes precedence over the others phpmyadmin will work. You can make it work by using different ports for each site. For example:

<VirtualHost *:8082>
...
<VirtualHost *:8081>
...
<VirtualHost *:8080>
...
