I just upgraded my Ubuntu server to 18.04.1 LTS (GNU/Linux 4.4.0-130-generic i686). I checked at command line and got "PHP 7.2.10-0ubuntu0.18.04.1 (cli) (built: Sep 13 2018 13:45:02) ( NTS )". When my designer went into Joomla admin page to check he got the following: Error We have detected that your server is using PHP 7.0.32-0ubuntu0.16.04.1 which is obsolete and no longer receives official security updates by its developers. The Joomla! Project recommends upgrading your site to PHP 7.1 or later which will receive security updates at least until 2019-12-01. Please ask your host to make PHP 7.1 or a later version the default version for your site. If your host is already PHP 7.1 ready please enable PHP 7.1 on your site's root and 'administrator' directories – typically you can do this yourself through a tool in your hosting control panel, but it's best to ask your host if you are unsure. I have this particular site set to "default" for PHP version. Am I missing doing something?
