Working on slider & portfolio suddenly homepage gone!

I don’t know what happened but suddenly my home link is linking to slideshow/ directory…

I deleted that entry so now I have a 404 on my homepage…

What I did:

– created a slider entry without a link

– created a portfolio entry with another image in the single post view (this was the first portfolio entry).

– Went to the slider entry and had it manually link to the portfolio entry through a url.

– then my homepage suddenly showed the portfolio entry in a single page view.

– So I deleted the portfolio and the slider entry and now I am stuck with a 404 on my homepage and the slider is gone.

– I also tried deleting just the link in the slider, that did not help either..

Will keep on trying things, if anyone has a brilliant idea I would like to hear it ofcourse.
