I am using this code to put some functions after content, but this one don't work. It appear before the content and not after.

function add_wb_posts_pagination ($content) {
        $content .= wb_posts_pagination();
        return $content;

}
add_filter('the_content',  'add_wb_posts_pagination' );

is the same code i use to add others functions, but this don't work...

what can be the problem?

wb_posts_pagination() seems to be a custom function that sends its output directly to the browser with echo or print.

Use a function that returns a string and does not create output to add that string to $content.

The printed output doesn’t wait, it goes into the page the moment you call that function.
