How to show a header and footer on the checkout page?

Yes, but i want to show the header and footer, any solution ?

solved,

I overwrite the checkout_index_index.php in my theme with the below code and header footer displaying.

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
    <referenceContainer name="header.panel" remove="false" />
    <referenceBlock name="top.search" remove="false" />
    <!-- <referenceBlock name="catalog.compare.link" remove="false" /> -->
    <referenceBlock name="catalog.topnav" remove="true"/>
    <referenceBlock name="navigation.sections" remove="true"/>
    <referenceContainer name="footer-container"  remove="false"/>
    <referenceBlock name="top.links" remove="true" />
    <referenceBlock name="top.links2" remove="true" />
    <referenceBlock name="minicart" remove="true" />    
    <move element="logo" as="logo" destination="ves_header"/>
    
    <!-- <referenceBlock name="ves.footer.top" remove="true" /> -->
</body>
</page>

You have to override check checkout_index_index.php file in your own theme. To do that create checkout_index_index.php in app/design/frontend/Demo/Yourtheme/Magento_Checkout/layout and insert this code in it:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
    <referenceBlock name="minicart" remove="false" />
    <referenceContainer name="header.panel" remove="false" />
    <referenceBlock name="top.search" remove="false" />
    <referenceBlock name="catalog.compare.link" remove="false" />
    <referenceBlock name="catalog.topnav" remove="false"/>
    <referenceContainer name="footer-container"  remove="false"/>
</body>
</page>

After it, don’t forget to run these commands:

rm -rf var/di/* var/generation/* var/cache/* var/log/* var/page_cache/* var/session/* var/view_preprocessed/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
php bin/magento cache:flush
