Change your login url for http://example.com/login and stop login brute force attempts.
Nop, sorry. I prefer keep the plugin as simple as possible. May be I'll consider it for a future version.
You're screwed! No, I'm kidding, but you need a ftp access to your site. When logged in with your ftp software, open the file wp-config.php located at the root of your installation. Simply add this in the file:
define('SFML_ALLOW_LOGIN_ACCESS', true); and save the file. This will bypass the plugin and you'll be able to access http://example.com/wp-login.php. Another plugin may conflict, you'll need to find which one before removing this new line of code.
Yes. Each blog has its own login page. The plugin must be network activated. Make sure permalinks are activated for ALL your blogs. In case the plugin fails to add the rewrite rules, there's a new "settings" page in your network admin area: "Settings" -> "SF Move Login". You'll be able to copy/paste the needed lines to your
.htaccess file or
web.config file, you'll need to edit it yourself with a ftp access.
Multisite and monosite installations does not have the same rewrite rules. Simply deactivate the plugin, and "network" activate it again. The new rules will be created.
