I made a fresh installation of the newest version of the WordPress in
Ubuntu Server 14.04 where the PHP version is
PHP 5.5.9-1ubuntu4.22 (cli) (built: Aug 4 2017 19:40:28)
I managed to install the WordPress site and a purchased theme successfully till now.
Will I encounter any problem with the site development?
I am asking because later I noticed this in WordPress requirements..
PHP version 7.2 or greater
