Same post in different URLs

I reproduce the bug if I manually type “site.com/post1.html” in the browser address bar. But is there somewhere a link that leads to “site.com/post1.html”?

I have found this bug when manually typed Url in adress bar too. Any other links I didn’t found.

The new development version should now solve this.

It works as redirection from site.com/post1.html to site.com/en/post1.html?
Most of post works good, but in some cases it returns cycle redirection when I try to go to site.com/en/post1.html.
This is an example https://pblog777.16mb.com/en/post-3-2.html

Is there something special with this post compared to the other which work

I added a protection against chained redirections similar to what is done by WordPress in such case.

In 0.9.5 it works :!)

Yes but it introduced a new bug ??

“/category/name/page/2” redirects me (301 – permanentely) back to “/category/name/”

I totally reworked this in the current development version (0.9.5.5)

I have tested 0.9.5.5.
It works ??

Thank you for your test!

It is an interesting thing. For post in default language (for default language prefix not used) site.com/post1.html URL address site.com/en/post1.html – still returns this issue. For post in non-default language (with prefix) such as site.com/en/post2.html and URL address site.com/post2.html redirection works correctly.
Canonical URLs in all cases – are correct.
Version 0.9.7. tested.

Sorry. I am not sure I understand what is exactly the issue.

With permalink : /%postname%.html
If en is the default language, and I enter site.com/en/post1.html, it returns 404

With permalink : /%postname%
If en is the default language, and I enter site.com/en/post1, it is redirected to site.com/post1

Is it this issue you are referring to?

Permalink : /%postname%.html
Default language – not English
Prefix used only for non-default languages.
site.com/post1.html – post in default language
site.com/en/post1.html – still returns post in default language but with English taxonomy.

site.com/en/post2.html – post in non-default language (English).
site.com/post2.html redirect to site.com/en/post2.html – it is right redirection.
Hm… May be it is impossible to do right redirection in all cases…

Now I understand. I did not cover this case. Could you try with the new development version (0.9.8.1)?

And yes you are right, I will probably not cover all cases.
