I changed wordpress address in settings and now i cant access it

I did something stupid and now I can’t access my blog.

I setup my Word Press blog at my root domain.com/weblog thinking I could simply change it to the root .com from admin settings once I was finished setting it up. Well I finished setting it up, and got rid of the /weblog in the admin settings, and now I can’t access anything.

To recap, I set it all up at example.com/weblog and then when I was done, changed the website URL and WordPress URL settings to example.com.

I had a look at these:
https://codex.www.ads-software.com/Editing_wp-config.php#WordPress_address_.28URL.29
https://codex.www.ads-software.com/Editing_wp-config.php#Blog_address_.28URL.29

But they didn’t help. I don’t have those values in my config file. I’m sure there’s a simple fix where I can revert it back to /weblog, but I don’t know how. Can anyone help?
