problem with sharing to facebook

Tick the box in Table IX-C3. If it still does not work, find out where the following code in your page comes from and try to get rid of it:

<!-- Start AL2FB OGP -->

add-link-to-facebook/add-link-to-facebook-class.php
it comes from this

Is that a plugin? de-activate it.

Did you tick the box in IX-C3?

Is a plugin, thanks for your help.
If I uncheck the open graph protocol (add link to facebook plugin) it’s working.

Cheers
