How to remove the demo gear on the customer side

Hi there, 
It seems your domain has a special case of DNS. To solve that issue, you can do these steps:

+ Open the XML file at: app/code/Ubertheme/Checkout/view/frontend/layout/default.xml
and find the code lines:

<referenceContainer name="main.content">
    <block class="Ubertheme\Checkout\Block\UserGuide" name="ub.checkout.user.guide" template="Ubertheme_Checkout::user-guide.phtml" />
</referenceContainer>

and replace it with:

<!-- <referenceContainer name="main.content">
    <block class="Ubertheme\Checkout\Block\UserGuide" name="ub.checkout.user.guide" template="Ubertheme_Checkout::user-guide.phtml" />
</referenceContainer> -->

+ Once done, clean M2 cache: php -f bin/ubdatamigration cache:clean

We hope that helps.
