Hi there. I changed my domain name in settings and then checked to see if it worked. It appeared to, other than HOME no longer worked. (I now realize that I set WordPress address (URL) to "http://www.helloremix.com" and "Site address (URL)" to "http://www.helloremix.com" when it should have been "http://www.helloremix.com/blog".)
So I went back into Settings and tried to change it back and the page went blank. Now, when trying to sign in, the page goes blank—so I can 't get into my dashboard or anything.
I tried the "Changing the site URL method" and the "Relocate method" found here: http://codex.wordpress.org/Changing_The_Site_URL, but neither worked.
Can anyone help me? I am very new to WP and not a programmer, but can follow instructions.
