Is this help https://github.com/mccalltd/AttributeRouting/issues/272

I am having the same issue with a fresh install of 3.20 with the sample database. Any idea where the problem could be coming from?

I can't be the only having this issue. I tried two separate development environments with the same results.

To produce this issue,
1. I download the source code version of nopCommerce 3.20 and install it using VS 2012
2. Log into Admin and create a language
3. Enable "SEO friendly URLs with multiple languages enabled"
4. Restart the application
5. Open the public store home page and you will see http://localhost:15536/en/ in the URL.
6. Click on any link and the URL will duplicate the locale http://localhost:15536/en/en/....

If believe the issue is coming from the GetVirtualPath method under the Nop.Web.Framework.Localization.LocalizedRoute namespace but the code appears to be the same as version 3.10.

Here is my System Info if anyone can help.  Thanks in advance!

Same problem for me for any link in the site.
It's also a problem when loading CSS and JS files too, they have the locale defined...

thanks.

Confirmed! I have the same problem too. Any idea on what is going wrong?

Any resolution?

I cannot reproduce this issue. It works fine on localhost and a live server.

What is your Windows version?
