Kirby requires the following:

- PHP 7.4, 8.0 or 8.1  
(PHP 8.0 is recommended)
- `mbstring` extension
- `curl` extension
- `ctype` extension
- `gd` extension

I’ve looked at my hosts CPanel and ‘curl’ and ‘ctype’ are not listed. See screen grab. What does this mean?

If those that are listed there are really all available (and not only those that you can enable/disable yourself), that would mean that your server doesn’t meet the requirements and that you will run into issues if you use methods that require these extensions. Use `phpinfo()` to verify.

Thanks. How do I use `phpinfo()` to verify?

In any template/snippet, just as a normal php function, then open this template in browser.

I don’t know what that means, but I’ve contacted my hosting provider and they have confirmed that curl and ctype extensions are enabled by default on all their servers. So I’m good to go!
