Question: I created an own template for WordPress 3.4.1 and got the problem that WordPress automatically(???) generates titles for every single page I create, but I don't want the page-titles as headline.

My template bases on the "Modern Theme" for Magento eCommerce. After adapting for WordPress it consists of footer, header and index.php and a style.css without attributes for page-titles. - Kind regards.

Answer: 
Remove the `<?php get_title() ?>` from the page.php and single.php.
Since it is a display issue, you should add `display:none;` to the corresponding css class or id, no need to remove `the_title` or `get_title`.
