After Deactivating Plugin – almost whole site dissappears..

Hello There,

Im trying to uninstall the bing translator from my clients site. But every time I deactivate the plugin almost whole site dissapears, just the background stays and the share buttons (please see screenshot here)

When I switch to default theme the site works.. only when its in the current theme we need its not working..

Here is the site link

Any advice would be much appreciated.

Thanks
