I am new here.
My client just sent me magento2 mega menu extention for setup and manage their menu and I installed it on their website but after installation their website gone down.
according to megamenu provider documentation I installed activation with the following commands.
first I run:
php bin/magento cache:disable
Then I uploaded files and after files uploaded i run this command:
php bin/magento setup:upgrade
then I run this command: php bin/magento cache:enable
after installation website gone down.
I'm getting this error
Exception #0 (Exception): Notice: Undefined property: Magezon\NinjaMenus\Block\TopMenu\Interceptor::$_helper in /mnt/data/home/202257.cloudwaysapps.com/tzpdyygggw/public_html/vendor/magento/framework/View/TemplateEngine/Php.php on line 110
