Elementor Header and Footer Created Problems to the theme page

Dear all,

I am using elementor Pro on my theme which supports elementor and I have created a header and footer.

While including the header and the footer on my website, the functionality of the core theme pages was affected.

In more details I get this message to a single page:

/wp-admin/admin-ajax.php 403
