I am pretty new in WP (I came from Joomla) and I have the following problem.
I have installed WordPress on my server and if I use one of the included theme (such as the Twenty Thirteen theme) when I open the website I see it and under the header I can see the classic horizontal Main Menu containing the voice Sample Page, ok...this is the right behavior.
Then I have installed the following theme http://bootstrapwp.rachelbaker.me/ that is a WP theme that use BootStrap (I think that it could be a good start point to develop a personal theme using BootStrap CSS framework).
I install it but when I activate the theme I obtain this result: http://onofri.org/WP_BootStrap/
As you can see the website is shown but seems that there is not the Main Menu as in the others preinstalled theme.
Why? What could be the problem?
I opened the header.php file of this theme and here I find the following lines of code:
<?php bloginfo('name'); ?></a> <?php wp_nav_menu( array( 'menu' => 'main-menu', 'container_class' => 'nav-collapse collapse', 'menu_class' => 'nav', 'fallback_cb' => '', 'menu_id' => 'main-menu', 'walker' => new Bootstrapwp_Walker_Nav_Menu() ) ); ?>
So it seems to me that the main menu navigation bar is present in this theme.
Do you have some ideas to solve my problem?
