Comment form goes to wp-comments-post.php

Begging for help here. I have been working on this for weeks, cannot find an answer.

I have 2 categories feeding in to a page. One category is fed in via magic fields. I cannot get comments to appear on that category and that’s fine. Another category feeds in via a regular post. A comment box now appears, due to this bit of code

<?php global $withcomments;
$withcomments=1;
comments_template();?>

however when I post a comment, the page appears blank and goes to wp-comments-post.php

There are no comment.php pages under dashboard>appearance>editor.

I’ve made sure comments are on etc under dashboard>settings and that it’s clicked under the post itself.
