Loading page failed

Hi,

I am using ajax filters 3.20 and every time I try to use the filter I get 'loading page failed' appear. I have read this forum post http://www.nop-templates.com/boards/topic/453/loading-the-page-failed/page/2 and the solution of changing the category template just doesn't seem to work for me. I was wondering whether there are any other solutions.

This is the error message I get in my log.

The parameters dictionary contains a null entry for parameter 'orderby' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Products(Int32, Int32, System.Nullable`1[System.Int32], Int32, System.String, Nop.Plugin.Widgets.AjaxFilter.Models.AttributeFilterModel, Nop.Plugin.Widgets.AjaxFilter.Models.SpecificationFilterModel, Nop.Plugin.Widgets.AjaxFilter.Models.ManufacturersFilterModel, Nop.Plugin.Widgets.AjaxFilter.Models.PriceRangeFilterModel)' in 'Nop.Plugin.Widgets.AjaxFilter.Controllers.WidgetsAjaxFilterController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters

Hi Matt,

Have you made any modifications to the category template. Can you please double check that the selectors for the orderby dropdown in the administration of the plugin is correct.

You can try re-installing the plugin, because if you have updated it recently without reinstalling, this may cause the error.

Looking forward to your reply!

Thanks for your reply.

Well, the site was developed by another guy and now I am just finishing it off but is customised. Does this make a difference? The settings are default and appear to be fine plus I only installed the plugin recently after we went to 3.20.

Cheers

Matt

Hi Matt,

If the category template had been modified and some selectors had been changed, you will need to enter the correct selectors in the administration of the plugin. In addition to that if you have modified the product-grid, you will need to make the same modification in the Plugins/SevenSpikes.Nop.Plugins.AjaxFilters/Views/Catalog7Spikes views.

If you can send us a link to your site we may see what might be wrong and fix it quicker. You can also send this information to our support email in case you do not want to share the link here in public.

Looking forward to your reply!

Hi there, I would send you the link but im working on localhost atm. How do I know by looking whether the selectors have been changed? Sorry, I am fairly new to nopcommerce and the plugins for it.

Regards

Matt

Hi Matt,

You can compare them to the default nopCommerce theme, i.e. defaultClean. By default is #products-orderby . You can easily check your html and see what is the selector for the order by dropdown.

You can have a look at the explanation in our online documentation.

Looking forward to your reply!

Oh okay, in which folder/file are they kept.

Cheers

Matt

Hi Matt,

Since we don't know what modifications you have made we can't advice.
Have added any new category or manufacturer templates in your store i.e CategoryTemplate.xxx.cshtml, ManufacturerTemplate.xxx?

Thanks

Hi, sorry I left it weeks before responding to tour help here. I have noticed changes between the original code and our modified code but stil cant seem to workout what I should change in the selector settings. Sorry to do this, but this is the section of code...I believe. in categorytempatesgridorlines

Hi Matt,

The forum isn't good for sharing code.
Please send an email at our support mail with your modified category template.

Thanks
