Hello, @Ritik Kumar,
Thank you for your response.
Following our recent correspondence, it has come to our attention that the issue you are experiencing persists even after the activation of the default WordPress theme. In light of this, we kindly suggest reaching out to WordPress support for further assistance. https://wordpress.org/support/forums/
We believe that once the matter is resolved in conjunction with the WordPress theme, it will consequently be resolved with our theme as well.
We appreciate your understanding in this matter and are here to assist with any additional concerns you may have.
Thank you for your cooperation.
Best Regards,
The 8Theme Team.
