To display the question title on each Q&A page:

1. Use the HTML `<title>` tag in the head section.
2. Set the `<title>` content to the specific question title.
3. If dynamically generated, ensure server-side code sets the title dynamically.

You will need to update the single-question.php page to display the title.

Try replacing the single-question.php file that can be found in the plugins/anspress folder.

Alternaytively, you can try reinstalling the plugin or check if anyother plugin/theme component is causing this issue.
