Prestashop – Error showing php "defien(..) code when entering the website

I have a Prestashop website and my Hosting has done some update that allow me to chose php version from the DirectAdmin panel,

but now after the change when I enter the website I see some php line of code with “define…” but all the rest is working fine in the website.

enter image description here

What can cause it? and How can I hide those line of code for the user?
