Okay,
THE PROBLEM:
I get "Error establishing a database connection" when I try to log in to change or update my http://www.doyoubelieveinvampires.com site or go to it.
WHAT I DID:
I was updating my site and when I was making a change to the subhead on the top of the Settings page (I believe that's where I was) on the Dashboard, I thought a field labeled "WordPress something" was empty that had been full when I went in, and filled it with the site address, which was in a field just below it. I should not have, but now can't get in to change it.
My WordPress site is hosted on GoDaddy, not on WordPress. I can access it with an FTP browser. I have backed up my MySQL database there as per their instructions, thinking I could edit the mistake out there since I couldn't find any files in the WordPress folder with the address in it. It may be that is where the instruction is after all, and I will restore my original MySQL database on GoDaddy until I find out otherwise.
If I just have to edit the misdirected web address out of one of the WordPress files, tell me which one, and I can do that and replace it with the FTP program. If it is in my database, does anyone know where? I can edit and resave that on the server as well.
Thanks!
I can answer any questions to get this up and running again.
