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. 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.
