Warning: file_exists() [function.file-exists] – help

Hi

I am having a sudden problem with this site

http://nordicgreen.eu/

I am wondering why there is some places in the error message where the path says …/wordpress….

The wordpress folder stille exists, but everything should have been moved to nordicgreen.eu root

The site has been wirking like this for about 2 years, and then this suddenly happened

Can anyone telle me how to fix this?

Looking forward to hearing from you 🙂
