On March 1st, 2020, that's only a month away, our extras will require at least PHP 7.2 following along with our PHP version support policy.
This change will immediately take effect on March 1st across all our premium extras.
While the majority of sites using our extras is now using 7.2 or 7.3, we're still seeing quite a lot of sites on 7.1 or before as well. Those will need to be updated soon. To check what sites may be running an older version, use the advanced search in SiteDash or see the list of your sites in your account.
