Hi Vik12,
Thanks for reaching to us.
First of all, I’m really appreciate your patience.
If you are using Woodmart Header builder cart element and Elementor Pro plugin, you need to disable Elementor Mini Cart template
that is designed to work with Elementor Pro under Elementor > Settings > Integrations > WooCommerce > Mini Cart Template and select Disable. https://take.ms/Ra7Cv
In case you don’t use Pro version, there is an issue with the 3rd party plugins or Cache plugins. Please clear CDN or cache and deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Regards,
