Good day sir / madam

I have a problem related to domain name, my first domain name is elementfx.com my exact website address is http://swsf.elementfx.com
Yesterday i changed this to swsf.x10.biz but the website doesnt appear the way it should be, so reversed back to my first domain which is elementfx.com but nothing change.
I build my site using cms ( wordpress)
I can't access my wordpress admin panel.
