Error updating EasySocial

Hi, I finally updated the EasySocial component on the above site and all seemed to go brilliantly - success messages everywhere. However, neither the backend nor the frontend are displaying correctly - see attached screenshots. I tried reverting to the older version but I now get this error message:
"EasySocial .require() .script('site/toolbar/notifications','site/search/toolbar') .done(function($){ $('[data-es-toolbar]').implement(EasySocial.Controller.Notifications); $('[data-toolbar-search]').implement(EasySocial.Controller.Search.Toolbar);"

I have now run the update again, and am back to the point shown in the screenshots. I have also cleared the caches, and gone through the process to discover and clear extensions which didn't go through the normal installation process.

I would very much appreciate your earliest possible response.

Thanks,

Toni
