Yesterday I was doing some admin on my wp site http://www.segatfinancial.com and noticed that when the site name was entered into google search the retrieved 'landing page' was not the correct home page and was somehow defaulting to this redundant page.
In my limited wisdom I tried to change both URL site addresses on the Generals Setting page from http://www.segatfinancial.com to http://www.segatfinancial.com/home to align landing and correct homepage.
When I hit ‘save changes’ I got booted out and "Internal Server Error"message appeared and I have been locked out ever since. Every time I attempt to log-in at http://www.segatfinancial.com/home/wp-login.php I get the same error message.
I have basic skills in this matter so any advice kindly accepted?
