[Plugin: wordpress-https] Redirect loop

Hey,

I wanna get rid of https (plugin: wordpress-https), am stuck in a redirect loop and have no ideas anymore. Due to this, the page is unreachable at the moment.

I tried to replace the .htaccess with a very rudimental and

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.mysite.com/$1 [R,L]
</IfModule>
# END WordPress

tried the define('FORCE_SSL_ADMIN', true); method. Both did not show any results.

The db-entries are all set to http.

Because wordpress-https just made trouble from the first day, I just want to get rid of it! Any comments very appreciated!

Thanks a lot in advance!
