Hello Nirasulanka,
We do not give a guarantee for full theme compatibility with all existing 3rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our basic support.
Could you provide URL of your site, temporary wp-admin and FTP access? We will check what can be done to help you.
To provide wp-admin access, you can create a new user account with administrator role via the Dashboard, and provide us with the username and password via the Private Content area.
To create FTP access, please contact your hosting provider for assistance.
Kind Regards,
8theme team
