(i missed you response. this is an update, hope you still watch this thread)
i checked the theme author’s website; and this page title link seems to be an unresolved problem.
changing the variable names from $title1 to $ptitle1 (etc.) seems to solve the problem; leaving the code with
// Build main site navigation from Organic Options
$ptitle1 = substr(get_option('organic_theme_page_one_title'),0,15);
$desc1 = substr(get_option('organic_theme_page_one_desc'),0,35);
$ptitle2 = substr(get_option('organic_theme_page_two_title'),0,15);
$desc2 = substr(get_option('organic_theme_page_two_desc'),0,35);
$ptitle3 = substr(get_option('organic_theme_page_three_title'),0,15);
$desc3 = substr(get_option('organic_theme_page_three_desc'),0,35);
$ptitle4 = substr(get_option('organic_theme_page_four_title'),0,15);
$desc4 = substr(get_option('organic_theme_page_four_desc'),0,35);
$ptitle5 = substr(get_option('organic_theme_page_five_title'),0,15);
$desc5 = substr(get_option('organic_theme_page_five_desc'),0,35);
// fetches permalinks
$page1 = get_page_by_title($ptitle1); $link1 = get_permalink($page1->ID);
$page2 = get_page_by_title($ptitle2); $link2 = get_permalink($page2->ID);
$page3 = get_page_by_title($ptitle3); $link3 = get_permalink($page3->ID);
$page4 = get_page_by_title($ptitle4); $link4 = get_permalink($page4->ID);
$page5 = get_page_by_title($ptitle5); $link5 = get_permalink($page5->ID);
so forget the previous respond.
good luck ??
