Manufacturer detail page not working

[MKI-Miro]

Dear All

When I click on manufacturer detail button https://www.penovepuzzle.sk/jumbo it gives me error 404
When I disable Language filter and code than it works.

What do I wrong? or how to find issue?

Thanks

You could check if all Your language files are UTF-8. There should be no files in other formats, ANSI for example.
