Feeling really stupid here... I haven't been using WordPress or any other similar site much (say almost never). I wanted to change my url to new one because my name has changed. I would eventually wanted to do it by redirect but since I was reading the instructions I saw that you chould just simply do it like this:
"The "Home" setting is the address you want people to type in their browser to reach your WordPress blog.
The "Site URL" setting is the address where your WordPress core files reside.
Well, I wanted to see whether it's this simple and changed the home url to http://www.lottahanski.com (new one) and left the site url to http://www.lottasoini.com (old one). Next moment I was thrown out from the system and cannot log in any longer, because the address is obviously not correct.
Sorry for this idiotism, but is there any way to get my (old) site back and to be able to update that again...?
