So I thought I'd do some playing around by adding a new blog to a subsomain I had created. I chose the subdom folder to upload and used godaddy to create new database and upload. I never thought it would completely overwrite 2 years of content on the main URL. I never thought to back up because I was sure I was uploading to subsom directory.
If there is a chance in he'll to undo back to yesterday's default, please can you advise a desperate fool
