Hi,

After upgrading from 3,70 to 3.90 I'm getting a lot of these errors in the log:

The parameters dictionary contains a null entry for parameter 'searchVendorId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult GetFilteredProducts(Int32, Int32, Int32, SevenSpikes.Nop.Plugins.AjaxFilters.Models.PriceRangeFilterSlider.PriceRangeFilterModel7Spikes, SevenSpikes.Nop.Plugins.AjaxFilters.Models.SpecificationFilter.SpecificationFilterModel7Spikes, SevenSpikes.Nop.Plugins.AjaxFilters.Models.AttributeFilter.AttributeFilterModel7Spikes, SevenSpikes.Nop.Plugins.AjaxFilters.Models.ManufacturerFilter.ManufacturerFilterModel7Spikes, SevenSpikes.Nop.Plugins.AjaxFilters.Models.VendorFilter.VendorFilterModel7Spikes, Nop.Web.Models.Catalog.CatalogPagingFilteringModel, SevenSpikes.Nop.Plugins.AjaxFilters.Models.OnSaleFilter.OnSaleFilterModel7Spikes, System.String, Boolean, System.String, Int32, Int32, Int32, System.Nullable`1[System.Decimal], System.Nullable`1[System.Decimal], Boolean, Boolean, Boolean, Boolean)' in 'SevenSpikes.Nop.Plugins.AjaxFilters.Controllers.Catalog7SpikesController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters

The customer creating all the errors is builtin@search_engine_record.com

When I upgraded I removed the old plugins and added the new folders. I've tried uninstalling and installing again - and I tried adding "Disallow: /getfilteredproducts" to the robots.txt but nothing has worked.

Otherwise the filters seems to be working fine. Any idea what I need to do to fix this?
