WildBil2Me: The site I'm running the blog on is http://www.spend.dk . After I changed the permalinks I could not access the blog OR the wp-admin.php file. I have tried resetting the database by deleting all the tables in it (blog is still under construction so not too big a loss) but with no luck. So now my database is empty.
Otto42: I have been looking for my .htaccess-file since Gangleri told me about it, but can't seem to find it. It should be in my root directory, right? Can it be a hidden file of some sort? I am using filezilla, can't find anywhere where I can tell it to show hidden files..
As most of you have stated, the admin files should not be affected - but somehow they did.
