The difference between ACF4 and 5 is that 5 no longer adds a default options page. To add the options page that used to be there by default (borrowing @ajhisbrill code)
f( function_exists('acf_add_options_page') ) {
// Adds ACF Pro options page that used to appear by default in the ACF4 add on
$globalOptions = acf_add_options_page(array(
'page_title' => 'Options',
'menu_title' => 'Options',
'menu_slug' => 'acf-options',
'capability' => 'edit_posts',
'redirect' => false
));
}
You may need to edit the field groups that are supposed to appear on options pages and reattach them to the correct options page. There are some changes between 4 and 5 that sometimes causes this.
