Don't asked me why I changed it. I wasn't thinking straight, thinking it would solve a particular problem on my site, but now I've got more on my hands than I can handle.
So now whenever I enter http://exonesis.com/wp-admin/ which is where the admin panel really resides, I get redirected and I can't change it back at all.
I have tried the instructions here: http://codex.wordpress.org/Changing_The_Site_URL but it doesn't work still. :( (I made sure I had no trailing slash after the URL.)
Any hints. Pretty please?! :'(
Just in case: I do have access to my SQL databases, I just need to know what to do. :'(
