I'm wondering if anyone has encountered the same issue with AjaxFilters on nopCommerce  3.10. This is a category with a very large number of specification options:

If you click on a filter on this page, it tries to apply the filter, but it ultimately fails. In addition, the filter becomes checked and does not allow you to uncheck it or select another filter. All other categories on the site seem unaffected. However, none of the other categories have a large number of specifications like this one.

Thanks in advance.

Hello Everyone,

I'm having a strange issue since I've upgraded my nopCommerce to 3.1 and installed the paid version of the plugins. Currently I use a combination of the following on our site

Anywhere Sliders
Instant Search
Cloud Zoom
Ajax Filters
Ajax Filteers
Product Ribbons
Quick View
Quick Tabs

I think it must be caused by the combination of plugins and whether a user is logged in or not. The problem is not consistent on all pages. For example... Some pages have issues with Anywhere Sliders while others don't (like the home page) Also, the problem goes away once someone logs into their account. Once you log in, everything works fine until you log back out. If you log in as the admin and restart the application, then the problem goes away whether you are logged in or not. The problem is there in both IE and Firefox. I have not tested on Safari or Chrome, but I suspect it is the same. Very strange.,,

On the Home Page:
Here I have Anywhere Sliders, the Mega Menu and Instant Search Active. I have two sliders that never fail. They are always working for me. However, the mega menu stops displaying images and I get "Image for Category XYZ" instead of a picture.

On the Contact Us Page, Login Page, and Registration Pages
Here I have Anywhere Sliders, the Mega Menu, Instant Search and Captcha at play. In this case, when the condition is present, the Mega Menu will not show images and the Anywhere Slider will not load images either. The only difference between this page and the index page is the Captcha. However, the Anywhere sliders have never failed on the index page and they do fail on the Contact Us Page.

Product Pages
My product pages have the Mega Menu, Cloud Zoom, Instant Search and Anywhere Sliders. On these pages the condition causes the Mega Menu and Anywhere Sliders to fail. However, the Cloud Zoom never fails. We have also implemented Product Ribbons recently that could have caused the issue but I am unsure.Quick Tabs are also used with no problem. Ajax Filtes are not used on these pages.

Category Pages
On catalog pages, We use Mega Menu, Anywhere Sliders, Instant Search, Quick View and Ajax Filters. The problem here when the condition is present is with the Mega Menu. I've never noticed the Anywere Sliders failing on the Category Pages.

Has anyone seen this behavior before...?
Any help would be much appreciated. This only happened since I upgraded to 3.1 and installed the new DLLs.

Thanks for your assistance.

I just signed up for your newsletter and received the discount code for 15% off my next purchase. I've tried to apply it to my shopping cart but it says that "The coupon code you entered couldn't be applied to your order."

I'm looking to purchase the nop-templates ultimate plugin collection for multiple sites. Why can't this discount code be applied?

First, let me say that you've done a great job putting together a quality set of plugins for nopCommerce. There is a lot of work that goes into this, and you should be applauded.

I do have a feature request for AjaxFilters. At this time, every product specification that is added to the products in a category appear in the filter. This is great, but if you have a large collection of specifications between all the products the list can grow to be huge and the page size grows accordingly...

Would you consider adding the ability to load a maximum number of specifications to the list and if the list is larger than that maximum including a "more..." or "view all" link to the bottom of the list that will expand it if the customer wants to see more within that specification filter? This would allow us to have everything available to the online customer if he/she wants to view it.

Another suggestion would be to allow the website admin to set the default state of the list upon page load - collapsed or expanded for each specification attribute...

Here is an example that shows both scenarios:

Notice that in the Manufacturer's filter only 5 manufacturers are shown initially. The user can then click the "See More..." link to show the rest of the manufacturers in the list...

Scroll down a bit and you will see that the following filters load collapsed by default:
- Memory Channels
- Memory Socket
- Pins

Thanks again for the great products, you guys are superstars when it comes to this stuff.




You may also want to look into something else in the QuickView. When a product variant has "Allowed Quantities" that have been defined, you get a dropdown box instead of an input box that is displayed. The formatting on that object is off and it rides a little higher than the Qty Label and the Add to Cart Button...

I fixed it by adding the following to QuckView style.css file...

    .quickViewWindow .qty-dropdown {
        width: 60px;
        height: 24px;
        line-height: 24px;
        font-size: 14px;
        padding: 2px;
        margin-left: 5px;
        margin-right: 0px;

You may have already corrected this on the 3.0 version. This is from version 2.8...

I had the same problem, and I don't think it is a permissions issue. It happened when I deleted a duplicate image I had inserted into the slider... Uninstalling and reinstalling isn't a real solution to this problem. It blows out all your sliders, and then you have to put them all back in. God forbid you don't have the original image files somewhere, because if you don't you will have to create them all over again.

Check out the first line in the error:
System.ArgumentNullException: Value cannot be null. Parameter name: picture at Nop.Services.Media.PictureService.LoadPictureBinary(Picture picture, Boolean fromDb)

There is a null reference there. Obviously something was orphaned in the DB. Uninstalling the sliders blows out the tables. Otherwise, your sliders would come back when you reinstall...

Maybe you should look a little further into this one?

Hello Everyone...

I'm finding the same issue with a NopCommerce 2.6 installation. The page renders fine with IE, Chrome and Safari. However, the issue is apparent with Firefox 14.0.1.

If you would like to see what we are experiencing you can view the following page: (remember to use Firefox 14.0.1)

I'm actually getting the same issue with another site under development using Nop 2.6. Both of these were implemented manually (not with automated integration or widgets).

I've verified that the css files are current. Not sure what else to check...

Thanks for your help on this.


Hello Everyone,

I'm having a strange issue with NopCommerce 2.6 and the Ajax Filters. Normally, when you integrate the filters, you still get the following dropdown boxes at the top of the category page:

Sort By
Display Number of Items per Page
Veiw Mode

I get lists displayed instead of dropdown boxes... They look like li elements with bulleted items that match what should be in the dropdowns.

My Sort By Dropdown looks like this:

Sort By        
• Position    
• Brand: A to Z    
• Brand: Z to A      
• Price: Low to High      
• Price: High to Low    
• Created On        

My Display number of Items to Display Dropdown looks like this:



•     2
•     4
•     8
•    12
•    24

Per Page


My View Mode Dropdown looks like this:

View As


• Grid
• List


It's like if the dropdowns were being rendered as list boxes... If anyone has any insight on this, I would be very appreciative.
