After updating wordpress to the latest version, the top menu broke - menu items are not displayed.

In the console such errors (404):

http://site.ru/wp-content/plugins/rti-slider/inc/functions.js?ver=4.7.2 http://site.ru/wp-content/plugins/rti-slider/inc/rtislider.css?ver=4.7.2

etc.

Who faced similar, in what m. problem?

PS Why is the version WP ver=4.7.2 indicated on the way to the file? Can it somehow affect?

UPD

The menu is displayed as:

 <?php $walker = new mainMenuWalker (); $args = array( 'theme_location' => '', 'menu' => 2, 'container' => false, 'menu_class' => nav, 'menu_id' => '', 'echo' => true, 'fallback_cb' => 'wp_page_menu', 'before' => '', 'after' => '', 'link_before' => '', 'link_after' => '', 'items_wrap' => '<ul class="nav navbar-nav">%3$s</ul>', 'depth' => 0, 'walker' => $walker ); //wp_nav_menu( $args ); wp_nav_menu( array( 'menu' => 2, 'depth' => 2, 'container' => false, 'menu_class' => 'nav navbar-nav', //Process nav menu using our custom nav walker 'walker' => new wp_bootstrap_navwalker()) ); ?> 

Maybe there is a mistake?

UPD

Debug displays such errors:

Notice: Use of undefined constant nav - assumed 'nav' in /home/g/genomq/site.ru/public_html/wp-content/themes/rti/header.php on line 76

Notice: Trying to get property of non-object in /home/g/genomq/site.ru/public_html/wp-content/themes/rti/include/wp-bootstrap-nav.php on line 65

    in which m. problem?

    In the absence of plugin files /wp-content/plugins/rti-slider/inc/functions.js /wp-content/plugins/rti-slider/inc/rtislider.css

    However, it is unlikely that the slider will be to blame for the "breakdown" menu.

    Why is the WP version ver = 4.7.2 indicated on the way to the file? Can it somehow affect?

    In the normal case can not. Only if some wrong protections / redirects are registered somewhere.

      wp_debug tried? Rather, the problem is that wordpress has been updated, some hooks have changed, for example, and the plugin has been written under the old ones, so now there is an error, as an option.
