Hi zaharovo,

Could you tell us which version of the Filters and nopCommerce do you use?

Best Regards,
Nop-Templates Support Team

I am experiencing the very same issue after upgrading my site to nopCommerce 2.50 (and ajax filters for 2.50). I hope I did not make a mistake at migrating my code.

The filters are displayed on my website, but when I use the filter, I get the javascript-message: "Loading the page failed."

When I look into the System-Log in nopCommerce, I see this message:

Page URL: http://localhost/catalog7spikes/getfilteredproducts
Short message: An error occurred when trying to create a controller of type 'SevenSpikes.Nop.AjaxFilters.Controllers.Catalog7SpikesController'. Make sure that the controller has a parameterless public constructor.

Any ideas?

Hi Christoph,

This error is due to an inconsistency between the SevenSpikes.Core and the SevenSpikes.Nop.AjaxFilters. Did you replace both plugins? If so please restart your application and let us know if you still have this problem!
