Hello, @Salah,
Actually, the issue you are facing on your site is not our theme issue but the third-party plugin compatibility issue, you are using on your site.
So you have to contact that plugin Author for help.
Otherwise, you can ask for paid Customization services, for making that plugin compatible with our theme.
Please note that we do not give a guarantee for full theme compatibility with all existing 3rd party plugins.
Thanks for your understanding.
Regards 8Themes Team.
