From one day to another all of my kirby websites that I host at dogado throw this error. They all use Kirby 3.9.7 and PHP 8.2.7.
I contacted the dogado support but haven’t heard back from them.
Weirdly some of the websites still render correctly when debug is disabled, but the error message (fatal.php from the the Kirby folder) is just added at the end of the page.
