I've installed the plugin, and a template and followed the intructions. WP Admin\Menus recognizes the menu I have added first from WP Admin\ Menubar, and I have attempted to add as instructed the following line at the 'end' of the theme's (Twenty Eleven) header.php file:
<?php do_action('wp_menubar','SuckerfishWoCSS'); ?>
I've tried at the 'very' end (doesn't make sense to me, but whatever...), just above <div id="main">, and just above the next line above, </header><!-- #branding --> but I continue to get the error on my Front page: "WP Menubar error: Menu 'SuckerfishWoCSS' not found! Please create a menu named 'SuckerfishWoCSS' and try again."
I've created it twice, and saved it and WP Admin\Menus lists it and whatever changes I make to it are registered in the actual menu bar on the Front Page, but I can get rid of the error.
Any suggestions will be greatly appreaciated.
