“Previous Entries”-link on mainpage is not correct and gives 404-error.

As said, “Previous Entries”-link on mainpage is not correct and gives an 404-error. My website is https://www.krugern.no and wordpress is installed in https://www.krugern.no/dev. The correct url in the link should be https://www.krugern.no/dev/page/2/, but is showing as https://www.krugern.no/dev/dev/page/2/. Where can I locate the appropriate string I need to alter? I have been looking around for a while, but I guess I am too annoyed by the problem to find it.. heh.

If I enter the correct url by hand the next previous entries link is correct..

And clues?
