arrowchat disappears when i enable cache in the config

$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] ['cache_dir'] = '/path/to/cache';
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] ['cache_id_prefix'] = 'xf_';
