How to force Wordpress to recognize new PHP 7.4 install in ubuntu

Question

I have installed php7.4 and installed all the packages and updates. Rebooted my droplet, restarted apache, cleared all caches, etc. My server is running php version 7.4. But my wordpress installation is still using PHP 5.x and warning me about needing to update. I’ve followed every how-to and tutorial. I tried to disable 5.x and the site broke. I’ve looked through .htaccess and wp-config.php, etc etc, there’s nothing conflicting or even mentioning php versions.

Anyone have any advice? is there a way to force wordpress to use php7.4? Where in the wordpress back-end does it even mention which php to use if it won’t default to the newest version?

Thanks!

Hi @todderik , 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 7.4 by disabling the old PHP module and enabling the new PHP module using the following command. sudo a2dismod php5.X sudo a2enmod php7.4 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 7.4 FPM sudo apt install php7.4-fpm After the installation has completed, confirm that PHP 7.4 FPM has installed correctly with this command php-fpm7.4 -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/php7.4-fpm.sock; Regards,KFSys
