I added a php code into a few of my files in Themes-Editor.When I pressed update a white screen came up so I had to press the back button to check if the update had worked, which it did. After I logged out I tried to log back in using http://www.voicesfromthevillage.co.uk/wp-admin but a white screen appeared. I then used an old link I had to the login page, but WordPress didn't recognise my username and password. I now can't access the Dashboard or even bring the login screen up. I've tried resetting my password but WordPress says neither my username or email address is registered to WordPress. So far every work around I've found requires me to login to the admin page, but I can't even do that.
