result of this problem is that the select boxes in the theme options dont work.
currently only these plugins installed:
WordPress MU Domain Mapping
WPBakery Visual Composer
Try to disable all the third-party plugins that did not come bundled with our theme (Akismet, WordPress MU Domain Mapping, WP Encrypt, WP Multi-Network). Very likely one of your additional plugins is not compatible with Redux.
In case after disabling problem still persists, reply back and provide admin panel and FTP access.
