Sending a request ends in a 404 error

The AJAX request of form results a:

Page Not Found
Reason: Request parameters could not be validated (&cHash empty)

Solution 1.

Open the Installtool and disable pageNotFoundOnCHashError setting: [FE][pageNotFoundOnCHashError] = false

Solution 2.

Exclude the parameters of the request like this (LocalConfigration/settings.php):

'FE' => [
    'cacheHash' => [
        'enforceValidation' => true,
        'excludedParameters' => [
            'theme',
            'simulateDay',
            'demo',
            'useSnow',
        ],
    ],
