So I made a bit of a mistake, I fear. I was trying to get my wordpress website to be accessible at http://www.developmentanddiabetes.com as opposed to http://www.developmentanddiabetes.com/home. I deleted the "/home" part on the site address in my settings in my dashboard.
That kicked me out of the dashboard and now when I try to access it at http://www.developmentanddiabetes.com/wp-login.php, I am sent to a page that reads:
The requested URL /wordpress/wp-login.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."
My website, http://www.developmentanddiabetes.com/home is also appearing now without the theme and mainly in text only form.
I may have made a big mistake! What can I do?
