This FAQ may apply to all Themify themes but has only been confirmed with their Magazine theme.
The theme has a visual page builder built in. This is a great feature to have. This particular visual page builder caches its output which is normally is a good thing. However, this simply will not work for highly dynamic shortcode based plugins like Connections.
The output of the Connections shortcode changes based on actions the user takes. Since the page builder caches the output, the only output from Connections that you will see is what was displayed when the page was first visited. This means that clicking links and performing search will appear not to work because the same content from the page builder cache will be displayed. This page builder cache feature seems to have been introduced in version 2.4.2 of their theme framework.
This can be fixed by disabling the page builder cache. Go to Themify > Settings > Themify Builder and disable the Builder cache.
