styles not loading

I made a header template using some of your weights in elementor. everything was working fine when i was editing in elementor in backend but when i see the template on the frontend it was broken. the menu was not working, search form is not okay. i guess the css and js of plugin is not loading on frontend. kindly help with it as soon as you can
