You cannot click Like for your own posts, so this is not an issue.
However, if you can't see them on others' posts either, please ensure you've configured the Can Click permissions in the button management screen in the AdminCP under DBTech - Post Thanks.
If you cannot see that screen, ensure you've been flagged as Super Administrator in config.php
Thanks, i give permission to another user and i got a solution, thanks !, but now i can see everything, but when i click in "like" i cant "unlike" like in other forums.
