Say Goodbye to outdated PHP Versions
PHP is one of the most popular scripting languages on the web. In fact, 70% of all websites that use server-side programming use PHP. That’s 8 out of 10 sites.
PHP also powers WordPress websites. But a big problem we are facing in the WordPress community is that many sites, businesses, hosting providers, and developers aren’t supporting the latest versions of PHP.
This is why WordPress 5.1 “Betty” introduces new features from the Site Health project to improve Security and Speed:
WordPress will now detect if a site is running on an insecure, outdated version of PHP and display a notice in the dashboard with information about how to update PHP.
It also includes checks for PHP version compatibility with plugins. WordPress 5.1+ will prevent users from installing plugins that require newer versions of PHP than they have running.
With JungleWP, you have nothing to worry about as we already upgraded your sites to the latest version of PHP 7.3. Not only will upgrading instantly improve your site’s speed and performance, but it also provides security and compatibility benefits, too.
