Hi horaci,

Could you try to modify you Global.asax file by simply putting a few blank spaces in it and save it.
This should trigger MVC update the new Controller of the Instant Search plugin.

Thank you, it works, I just opened a plug-ins AjaxFilters and NopQuickTabs that had the same problem. But I have another problem - for all plugins I set the Enable Automatic Intergation, but in nopCommerce it not reflected.

Hi horaci,

Please note that the Automatic integration works only in the DarkOrange and nopClassic themes. In all the themes that we offer the plugins are already integrated manually and the automatic integration will also not work.
If you are using a different theme then you should integrate the plugins manually.

Hope this helps!
