I am currently the website admin for a small PTA group. I was trying to create a new website using wordpress. While I developed the new site, I wanted to leave the old one alone. I was under then impression that I could just go back and change the siteurl when I was ready, but now that doesn't appear to be the case.
My site is currently installed at example.com/blog but I want to access it via example.com instead.
I have looked at the Codex examples and it appears that I just need to change the site url and move and update a few files to my root directory, but whenever I go to change the site url, I get a pop up telling me not to change that and it doesn't let me change it at all.
How do I change my url? Do I need to move everything to root?
