That's a PHP (code) error, but I'm not seeing it. Do you have to perform some action before seeing the error, besides simply viewing the page?

Maybe some admin already fixed it :/

You need to remember to decode those HTML entities just before displaying them on the site . . . type "kirby"(no quotes) into the search box at the top of the site, for example, and see the glorious 039s.
