Can not chose Frequency

$schedules = wp_get_schedules();
$first = true;
foreach ($schedules as $key => $value) {
if(isset($value[“wpfc”]) && $value[“wpfc”]){
if($first){
echo “<option value=”>Choose One</option>”;
$first = false;
}
echo “<option value='{$key}’>{$value[“display”]}</option>”;
}
}

It works like that. Another plugin causes this issue. Another plugin resets the value of wp_get_schedules().

Can you try it after disable the all plugins please?
