Hello, Techgaon,
Thank you for the response.
Please update the theme and Core plugin – https://xstore.helpscoutdocs.com/article/63-theme-update https://xstore.helpscoutdocs.com/article/37-plugins-update
We need FTP access also, so our dev team can check the situation more deeply on your site. We do not have this problem on our own test site.
To create FTP access, please contact your hosting provider for assistance.
Thank you for your cooperation and we look forward to hearing from you soon.
Kind Regards,
8theme team
