I acidentally changed the secret keys in my blogs wp-config. Was using the template from my already existing and working blog, by download the config file through filezilla, and then edit it, to upload on my new site. and when I was supposed to upload the new config-file to my new site I happened to upload it to my already existing where I downloaded it from. And now I get "cannot establish connection to database". I guess it's because I also changed the secret keys in the file just to be sure. And I don't remember what secret keys I had before.
Anyone know what to do? Is there any way to fix this/reinstall without eraseing data from the database? don't want to loose my already existing posts if possible.
