Comment shows 404 error

Hello

First of all, thanks for this plugin. I have had so much problems with qtranslate last few weeks.

I try to use wp comment with “Business Directory plugin”. In the page, the form use the right address : <form action=”https://mywebsite.com/wp-comments-post.php&#8221; method=”post” id=”commentform” class=”comment-form”>

When I click on submit button, a 404 error appears with the following address : https://mywebsite.com/fr/wp-comments-post.php. Same problem with a comment on standard article. If I write on the address bar https://mywebsite.com/wp-comments-post.php, there is no error (but nothing is executed). I confirm to have wp-comments-post.php file in my root directory.

I’m using french (default) and english. My htaccess is :

Options +FollowSymLinks
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://mywebsite.com/$1 [R,L]

Is this problem related to qtranslateX ?

Thanks for your answer.
Pat
