An update to the droplet PHP has worked but wordpress still has lower version.

Hi @tom57746c21d00f ,

You need to tell Apache/Nginx to use the newly installed PHP verson.

Apache

You need to tell Apache to use the installed version of PHP 7.3 by disabling the old PHP module and enabling the new PHP module using the following command.

sudo a2dismod php5.X
sudo a2enmod php7.3

Remember to change 5.X with your actual PHP version.

Restart Apache for the changes to take effect.

sudo service apache2 restart

Nginx

For Nginx you need to install FPM, execute the following command to install PHP 7.3 FPM

sudo apt install php7.3-fpm

After the installation has completed, confirm that PHP 7.3 FPM has installed correctly with this command

php-fpm7.3 -v

For Nginx you need to update the PHP-FPM socket in your Nginx configuration located inside the sites-available directory. This will be located inside the location block location ~ \.php$

sudo nano /etc/nginx/sites-available/your.conf

The line you need to modify will look like this…

fastcgi_pass unix:/run/php/php5.X-fpm.sock; 

You need to replace the old PHP version with the new version.

fastcgi_pass unix:/run/php/php7.3-fpm.sock;
