upgraded to 2.5.1, blog links broken

Hello everyone,

When I click on a link in my blog, for example the comments link, or even the header (e.g., the title of the blog post), I am faced with a error message like…

“Not Found

The requested URL /2008/06/07/ramen-in-jyuugaoka/ was not found on this server.”

For example. Access https://www.japannewbie.com/ and click on “Ramen in Jyuugaoka”, and you will see the error message.

This is severely crippling my blog as no one can leave comments now.

Could anyone give me a hand?

I have tried updating the permalink structure but it had no effect. Any help greatly appreciated!
