Not possible to add comment to attachment in Twenty Ten

[pavelevap]

Using latest trunk, no plugin.

I inserted image into post with link to attachment page. Then tried to insert comment to this attachment, but I was only redirected to blank page (​http://localhost/Wordpress/wp-comments-post.php) and comment was not created. Adding comments to posts etc works well.

Can't reproduce on my install. Are there any notices with WP_DEBUG enabled?

Strange, I am using latest trunk for WP and Twenty Ten, all plugins deactivated (no .htaccess - basic permalink structure).
When I am logged in then blank page appears (WP_DEBUG shows no error).
When I am logged out then "Not found" appears.

Clicking on ​http://localhost/Wordpress/?attachment_id=11682 when logged out:

Chrome:

I am not sure what could be wrong? Main difference is probably in Apache code for wp-comments-post.php (200 when adding comment to attachment and 302 to post).

Using xampp, PHP 5.2.6, Apache/2.2.9. But it is my first problem with WordPress on this configuration (using more than one year without change). Thank you for your help...

The lowercase P in your directory is making me cringe. I would try to fix that. :-)

The access logs won't help much -- we need to know the PHP error log. Add define('WP_DEBUG', true); to wp-config.php. This should reveal the errors that are causing the blank page.

Strange, after update to latest trunk this problem disappeared...

Sorry for bothering you, closing ticket...
