It Works!

Hi

Ive installed CI on my Mac, along with a website i developed. The site has been working happily on a windows server. I had to update the version of PHP to 7.3 which meant I had to move the server to a Linux OS. Once moved the site stopped working, i.e. nothing is displayed. So to help debug the issue i installed on my mac.

When i go to localhost in my browser, all I get is a page which says 'It Works!'. I can't find the phrase anywhere in CI, does any know where that comes from?

Thanks for any pointers!
