 * Hi,
 * I am seeing the following error after installing Orbit Fox by ThemeIsle.
    PHP
   Version: 5.6 Tested with WordPress version: 5.0 and 4.9.6
 * Deprecated: The each() function is deprecated. This message will be suppressed
   on further calls in /public_html/wp-content/plugins/js_composer/include/classes/
   core/class-vc-mapper.php on line 111
 * Fatal error: Uncaught ArgumentCountError:
    Too few arguments to function Mfn_MegaMenu::
   mfn_edit_nav_menu_walker(), 1 passed in /public_html/wp-includes/class-wp-hook.
   php on line 286 and exactly 2 expected in /public_html/wp-content/themes/betheme/
   functions/theme-mega-menu.php:48 Stack trace: #0 /public_html/wp-includes/class-

 * I have removed the plugin for now, but I want to use Zelle Lite theme by themeisle
   and this plugin is needed for certain features.
 * Any help in order to resolve this would be great!!
    Thanks, Ani
