Mm…a priori Wholinks is designed to avoid mistakes, but hey, sometimes it fails….
There are hundreds of CMS, millions of editors… and each one puts the links as they see fit, so, although we have screened most of them some may escape us.
The process of Wholinks works like this: if a URL or a link returns an error, it will be checked 3 more times. There may be a server error or whatever, we have foreseen that, but if you see that persists contact us and tell us the error so we can fix it.
With your feedback we improve the tool for everyone 🙂
