Ok I followed all the steps you listed and changed it back to the original URL... but now when I try to login to the wordpress admin blog for the site, it still re-directs me to one of the other websites. I don't know what I'm doing wrong here. I'm sure this is an easy problem to fix but unfortunately I'm a newbie and the girl I hired isn't really doing much to help. You guys have helped much more than she has!
Does it take some time before the change takes place or is there any other steps that I'm missing here? Because the site I was working on for a client was a hidden link which is: http://www.Tilamerch.com/Shop I was almost done with that until I changed the URL in the general settings because I thought by doing that it will automatically list the site domain as another one that I want to link it to. So I've done everything you listed here, but now when I try to login it still won't let me login to the original WP site I was working on, but instead is still re-directing the login to the other website URL that I initially changed it to. Plus the entire website layout and design is still messed up! Is this something I will also have to re-configure and fix once the URL has been put back to the way it was? Because my original design looked exactly like this: http://demowp.templatesquare.com/fashionistyle/
And now it looks like this: http://www.Tilamerch.com/shop
Thanks I really appreciate everyone's help. I'm on a tight deadline here and I just wish I can get the website back to the way it was! ahhhh!
