This means the hook listener is executed every time the core does not find a function. PostCalender than has the following lines:
if (!SecurityUtil::validateCsrfToken($token)) {
throw new Zikula_Exception_Forbidden(__('Security token validation failed', $dom));
}
These throw an error mostly, because there is of course no csrf token. This results in an empty page with the only message: Security token validation failed.
So please remove or change the way the function works or remove it entirely (For me it looks like some outdated Hooks stuff?).
HookHandlers::postcalendarhookconfigprocess()
