WordPress Multisite not detecting php7

  • hi, been struggling with this issue for months could not figure it out. I think originally we set up dual versions of php something like 5.3 and 5.6. Since then updated to php 7, but our wordpress multisite installation isn’t seeing the php7 and still thinks the server is running php5.x, keeps giving us update warnings. We even checked the phpinfo in that domain, it also says its on php7. We are out of ideas, hoping someone here has encountered a problem like this before, it would be greatly appreciated!

    This will help you upgrade to 7.3.

    This is what I use to install PHP for WordPress.
    sudo apt install php7.3 libapache2-mod-php7.3 php7.3-common php7.3-mysql php7.3-gmp php7.3-curl php7.3-intl php7.3-mbstring php7.3-xmlrpc php7.3-gd php7.3-xml php7.3-cli php7.3-zip
    I have been working on better securing my web sites in WP. I installed the Health Check plugin.
    It checked the php components and found a few missing. CURL, which I had installed so I refollowed these steps to verify it for php 7.3

    First Install CURL by typing sudo apt-get install curl
    Then Restart Apache by typing sudo service apache2 restart
    Then Install PHP5 CURL by typing sudo apt-get install php7.3-curl
    will prompt to install… type y or yes!
    Then Restart Apache by typing sudo service apache2 restart
    Done! It now shows up in phpMyAdmin.

    I have upgraded to the latest LAMP components that you are read about on Ubuntu pages. I am on the latest version of WordPress. This mainly affects my main webpage with videos of my children. These files can be huge.
    /etc/php/7.3/fpm/php.ini
    /etc/php/7.3/apache2/php.ini
    upload_max_filesize = 768M
    post_max_size =768M
    memory_limit = 768M
    max_execution_time = 360
    Health Check said these two components were missing. fpm had some errors too.
    sudo apt-get install php7.3-bcmath
    sudo apt-get install php7.3-imagick
    I ran the commands below in various order to fix fpm
    sudo a2enmod proxy_fcgi setenvif
    sudo a2enconf php7.3-fpm
    sudo apt purge libapache2-mod-php7.3 libapache2-mod-php
    sudo apt install libapache2-mod-php7.3 libapache2-mod-php
    After I fixed these errors, I ran update and dist-upgrade again to get the latest versions.
