404 Admin Error

Question

I am new to WordPress and was looking at settings in the admin. I believe I changed the directory of the site from example.com/wp/ to example.com. When I saved the changes I immediately saw a 404 error that says:

Not Found

The requested URL /index.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

In trying to fix what I messed up I came across this question which an answer said to Delete .htaccess however I believe the root cause in that question is different than my problem.

Answer 1

I found the solution.

I had to open up phpMyAdmin open up the database then open up wp_options. From there I had to change the siteurl and add /wp to the end and it works again.
