Whenever a reader submits a comment instead of refreshing the page and displaying comments, they get a 404 error. In the address in the tool bar is showing a double // so I assume that is the problem but I can't see how to fix it. I am looking at the code

PHP Code:

<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">

but not sure how to correct it or even if I am in the right place.

Any assistance is appreciated.

That code looks alright. The comments go through and get posted, the second slash is being inserted by the browser, the error starts before the comment form, with a wrong link TO the comment form

Note the space before #comments

Both the (main) links to posts (via the post headlines) and the direct links to the comment area of posts have a trailing space.

There appears to be a trailing space somewhere in your settings, see if there's a trailing space at Site Admin -> Settings -> Permalinks -> Custom Structure

Click into the right edge of the "Custom Structure" text field and see where the cursor ends up at. If there's a trailing space, delete it, click "Save changes" and try posting a comment again.

Thank you, that fixed it. I added it a kudos to you in the comments there on the blog.
I was looking for a way to mark this thread as solved now but I didn't see instructions in the FAQ.

Flynn,

Could you share some insight on my blog? All of a sudden, my visitors are getting the 404 error when they submit comments. Not sure how this could happen suddenly. This is the error page they're getting:

My wp-comments-post.php file is present. I even reuploaded it from WordPress.org. So I have no idea why I'm suddenly unable to get comments to go through.
