When you develop a new them or customize a theme then in certain case we don't see admin bar from frontend of the site though we logged in to backend admin panel. This happend because you are missing to call get_footer(); in the template.
Please do the below task:
Open index.php, footer.php, archive.php, author.php, category.php, image.php, page.php, search.php, single.php, tag.php etc file into notepad++ and place below code in there:
That should solve your problem.
