No, I don't think you missed anything. Can you check if, when hiding the URL segment for this document type, you end up having two nodes with the same URL?

Nope, It happens to all of this Document Type descendants...

It did effects the links to this descendants but all pages gives 404 and the error I mentioned...

That's strange.

Have you tried to:

1. Touch web.config to reload the application
2. Republish entire site to recreate the cache
3. Publish all descendants?

Yes, already tried that :(

I'm curious now. The only case I've seen such an error is when there is a URL collision (duplicate URLs). If you've checked and you are sure that there isn't any such issue, then maybe it's something new that I'm not aware of. What happens if you remove the setting from your web.config? Do URLs behave normally?

Also, is there any chance that the 301 url tracker is causing the issue? Any strange redirects there?

Oh my. Truth is I never tested it with non-English characters. It's time to try it with Greek then :)

I suspect the problem lies in the fact that the request to the server gets percentage-encoded when using Unicode characters. It will need some testing.

BTW, I usually convert non-English characters to English since I'm not very convinced that non-English characters are good for SEO.

Oh, Great! I will follow for an update, thanks!

About the SEO - it depends on the characters the users use, if they search for a Greek phrase, It make sense that it would be good to have it in the URL...

Hi Sotiris, any updates about this feature? The Greek nation is looking forward :)

Have a look at https://our.umbraco.org/forum/using-umbraco-and-getting-started/84415-this-document-is-published-but-its-url-would-collide-with-content-error#comment-267367 and http://issues.umbraco.org/issue/U4-9442

I think it's related with this: http://issues.umbraco.org/issue/U4-9430

If you're getting the "url would collide with content" error you could try the Url Preview package: https://our.umbraco.org/projects/backoffice-extensions/url-preview/

It will show the URLs instead of the error.

I apologize for not being able to answer things here during the last few weeks, due to a very demanding workload. This is ongoing, so I'm afraid I won't be able to check things for a few weeks more. I promise to debug (and adapt everything to 7.6 if needed) as soon as workload lessens a bit.

Awesome, we'll hold patiently for it :) thanks!

I will add, i found this error even before i installed DotSee.VirtualNodes. Before package i have implemented simple UrlProvider. So error "This document is published but its url would collide with content (error)" will not be connected with plugin but it may be a core error (im not completely sure).

public class CustomUrlProvider : IUrlProvider
    {
        public string GetUrl(UmbracoContext umbracoContext, int id, Uri current, UrlProviderMode mode)
        {
            var content = umbracoContext.ContentCache.GetById(id);
            if (content != null)
            {
                return "/" + content.UrlName + "/";
            }

            return null;
        }

        public IEnumerable<string> GetOtherUrls(UmbracoContext umbracoContext, int id, Uri current)
        {
            return Enumerable.Empty<string>();
        }
    }

When i istalled plugin, error disappeared.

I'd like to add that if you do not have a Content Finder implemented for your UrlProvider, you will get the duplicate url error (which is the wrong behavior I think?). This comes from Umbraco trying to route the request to see if it is a duplicate url.

Well, I do not see how what both of you wrote have to do with the problem I described. I did not use any UrlProvider, only VirtualNodes and only when I use non-English characters as name of the nodes I get the error....

@Sotiris - any update that solves this is planned soon?

Oh, now that makes sense. Thanks Alessandro.

Update here if it would be fixed please...

did anyone find a solution to this? I am on v7.6.6 and i am getting this error when there is a french character in the url. Once i remove it, the page works.

Hello,

I'm getting same message(This document is published but its url would collide with content (error)) for Link to Document in Content for all nodes.

I don't have any non-English character in URL. I just upgraded Umbraco from 7.4.0 to 7.6.0 and getting this error.

Any idea/suggestion?

There is no fix yet. This post explains a bit more why: https://our.umbraco.org/forum/extending-umbraco-and-using-the-api/86109-urlprovider-causes-url-would-collide-with-content-error

You can still try my Url Preview package: https://our.umbraco.org/projects/backoffice-extensions/url-preview/

Ok sorry guys i am still confused with this, so exactly what is causing this :) i have a new site running v7.7.4 and i don't have any other languages except the default english-us , all nodes under my home node are fine, its the others under my settings and from that document and all its descendants they all have this error.

I have installed @jeroen URL preview, and there definitely is nothing funky on the URL, pretty standard i think, see attached images. At least in my case these are not actually view-able pages and are just info/setting providers.

I have the same problem.

Set useDomainPrefixes to true in umbracoSettings.config helped me:

<useDomainPrefixes>true</useDomainPrefixes>

This PR fixed the issue for me.

https://github.com/sotirisf/Umbraco-VirtualNodes/pull/8

I know it's on old issue, but we still have this problem with hebrew characters on the V8 version. If there is any fix/solution/update ,we'll be glad to hear :-)

Still have the same issues with Umbraco version 7.15.7 assembly: 1.0.7706.20570

is working on a reply...
