Bad url

[title de-capped]

Hi – I’m new to WP. I was able to get my site up and attempted to set up multi-language for the purpose of having multiple audiences. But, when trying to view the site, I get this error.

Not Found

The requested URL /en_US was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

When I refresh the browsers, or manually remove /en_US my site comes up.

Not sure what I did that is causing the issue.

Any assistance would be valuable.

Thanks in advance.
