Wordpress Site URL name change crashed site

[Metcalf]

I needed/wanted to change the website address name... So I typed the new name into Wordpress Address URL and Site Address URL and after I did that it seemed to destroy my ability to open my website or even access the ADMIN area to correct it... I'm at a loss because I have no idea what I'm doing (obviously!).

Is there anyone who could possibly help me?? PLEASE!

The site is: www.crossfitsansreproche.com

Please let me know what I can do to fix, if anything. 

Thanks!

As WordPress is a completely web-based application it would need the proper URL in order to work, even the admin area.  Though there are a few alternate methods of changing the URL if you are locked out.

Thanks for the reply! I’ll try to figure it out. Wish I knew someone who was good with this stuff. 😊
