Problem with wordpress login page

My website was working fine up until about 4 hours ago and then, all of a sudden and with no changes to the site on my part, the Wordpress login page broke.

When you try to browse to it you are told that the page cannot be find. I have checked through FTP and it is still there. This is a real pain as we have just relaunched the website and have done a big marketing push.

Any ideas would be greatly appreciated.

Does this mean you can’t get to wp-admin?

If you have a .htaccess file (it’s hidden), rename it to .htaccess.old and see if the site works. You can re-create .htaccess by going into wp-admin and using the Permalinks option again.
