Running an older version of PHP on your WordPress site? If you're hosting with SiteGround, I'll show you how to update your PHP version using cPanel in SiteGround.
SiteGround offers PHP 7.3, 7.2, 7.1 and 7.0. I HIGHLY RECOMMEND you use 7.3, but 7.2 is also OK.
Updating to PHP 7.3 will provide significant performance improvements, as well as keep your site secure.
In this video, I show you how to run some tests before updating, and then use SiteGround's cPanel to update your PHP version.
