Error.log is empty. My Firebug gives the message
There seems to have been a technical problem. Please click the back button, refresh your browser, and try again.
wich can be found overhere: (/framework/forms/Form.php)
public function httpSubmission($request) {
$vars = $request->requestVars();
if(isset($funcName)) {
Form::set_current_action($funcName);
}
// Populate the form
$this->loadDataFrom($vars, true);
// Protection against CSRF attacks
$token = $this->getSecurityToken();
if(!$token->checkRequest($request)) {
$this->httpError(400, _t("Form.CSRF_FAILED_MESSAGE",
$request."There seems to have been a technical problem. Please click the back button,"
. " refresh your browser, and try again."));
}
....
}
But I don't have any idea why it is not getting the token, because it seems to be in the $_POST
