How to remove top menu in check out page

Hi There,

Please go to the file: app\design\frontend\Ubertheme\megamall\Magento_Checkout\layout\checkout_index_index.xml at line 10 and modify as follows:
Replace: 

<move element=”logo” destination=”header-wrapper”/>

With: 

<move element=”logo” destination=”header-wrapper”/>
<referenceBlock name=”catalog.topnav” remove=”true”/>

Once done, please clean the cache in Magento System.
Please let me know if you need help further.

Best Regards,
Ziven.
