Method not allowed when posting comments

I am currently using jetpack wordpress comments on my site – when you post a comment on a specific picture (carousel) it works fine but if you try to comment on a post it gives the error: Method Not Allowed

The requested method POST is not allowed for the URL /dm/wp-comments-post.php.

I have read some forums saying that you can’t post a comment to an html file and it needs to be a php file – based on this error it looks like it is trying to post to a php file. In all honesty I wouldn’t mind just removing the comment function on posts themselves – to me it’s fine if people can just comment on specific pictures – is there a way to fix it so people can comment on posts or just a way to disable the comment feature on pages where it won’t allow you to comment? Thank you in advance for the help!!! my page is https://www.daily-mash.com – thanks!
