Help needed, can't login

Hi,

You’ve a great plugin, but i always face an issue, if after install the plugin, and if I forget or didn’t change the permalink, I would have a problem login.

When i try to login, it redirects to http://www.example.comcustom-login/
then the following message will appear -> This webpage is not available
now i can’t even access to my wp-admin area, what should I do now? Please kindly help or advise, this will always come back when you deactivate and reactive the plugin again, please kindly help and advise what to do?

My htaccess content is

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteRule ^custom-login /wp-login.php [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

I’ve tried to remove

RewriteRule ^custom-login /wp-login.php [QSA,L]

but it’s still not working
