It doesn’t let me choose the php version, the button does nothing. I want to modify some php setting but it doesn’t let me change the version
I just checked, clicking the button works fine for me.
Try reloading the page, clearing cookies and cache or trying it with a different browser.
Alter PHP Version button is supposed to bring you to a page where you can set the PHP version of your account. What happens when you click the button (i.e. what does “nothing” mean to you)? Does the page change at all?
