As far as I see for some reason all the posts have the same wrong address, but there is no bug with the get_permalink() function, so my guess is that the: $post->ID is the ID of the page and not of the post. Try to print the $post->ID and to see what it prints, my guess is that it will print the page ID.

Hi, Is that a page using a page template? Because it is using the same post id for all your added button permalink. If it is a template, you should add your button codes within the template's WordPress Loop and not using add_filter in the functions.php Thanks. Denzel

Hi, The site not viewable without login.. :D You should use 'excerpt_more'. the filter should be add_filter('excerpt_more', 'your_function');
