It tookme a long time to understand why, too. After a lot of searching I realised I needed to delete (again) the wordpress files from the database, then from my computer, redownload wordpress, reupload the wordpress folder content (but not the wordpress folder itself) to the database and then reinstall the wordpress. I had some trouble with reinstalling but got help from this topics last post:
So there. I got it. http://www.varangerworkshop.no is now up and running! :D
I am very grateful for all your good advice. I only didn´t understand it very easily as Im totally new to this. Thanks!
