Some hosting companies like “1&1” offer a pre-installed WordPress version, but sometimes this WordPress version is modified. If you can’t see the link “Theme Options” in WordPress admin -> Appearance, please check if you can see the “Edit Theme” link in the same path. If not, your hosting provider has installed a modified version of WordPress and you don’t have the full admin rights. Please ask your hosting provider for the full admin rights for the WordPress installation.
