If your PHP website is reporting an Internal Server Error all of a sudden, this might be related to the switch from
PHP 7.4 to
8.0. Check if your site works again if you switch back to
PHP 7.4 and then try updating your PHP software to a version that supports
PHP 8. Don't hesitate to contact firstname.lastname@example.org if this doesn't help.
PHP 7.4 will be available on our servers until end of February.
