I've been working on my website lately and in the settings menu I tried to change the URL appearance. It was set on 'http://younghighpotentials.nl' and I changed it to 'http://www.younghighpotentials.com'. The .com domain is also registered on my name.
I've changed this in 2 fields, but I can't remember their exact names though. However, the moment I changed this I'm not able to enter my wp-admin interface anymore and when I request a new password it doesn't recognize my old username.
What to do now?
