I changed my website and nameservers which has caused my blog to no longer work. I'm trying to figure out how to move my blog to a subdomain but can't get it to work. I even did a fresh install onto the subdomain and even that isn't working. I'd so hate to lose everything on the blog. Any ideas?

I think you need to copy the SQL data (from mysqladmin or something like that, in your cPanel)
export the sql data from old server, then import to new one

I got it working. Now I'm slapping my forehead saying "DUH!" Some days my brain just doesn't want to work correctly and I just won't heed the message lol. All I had to do was change the baseURL in the basic_config php file. I kept trying to copy/paste with re-install, and play with mysql. I made something really simple into something really difficult.
