Some hosts allow you to change the PHP version when you log in to their Control Panel, but just because you use Varsion 17 of X5, it does NOT mean that your PHP changes automatically! I had to ask my host for the ability to change PHP and they only applied it to one of my 3 sites.
(IT > En) ... v.17 requires the minimum version PHP / 5.6 or higher; ... PHP / 7+ is fine...
... you can check in your online panel the PHP version you have on the server: www.yoursite.en/admin/
