few problems

Also, you can disable the plugins to check the issues. If you still face their issue, please send me username & password of your site for further checking.

i have tried inserting the code above and it didn’t help at all (the problems above still persist).

i want to emphasize that only in the desktop view, the comment box in the question part is hidden. but in the mobile view it is shown. this is the most important problem for now.

is there any code i can add that deals with the mobile view problem?

Please send me username & password of your site for further checking. I have checked on our demo with the my code and it works fine.

how can i send it privately?

You can use the private answer: http://prntscr.com/dgarfx

thank you.
the voting counts were indeed removed. is it possible to also remove the “sort by votes” option?

also, the problem regarding the comment box in the question section in mobile view is still showing. can you help me hide it in mobile view? (the comment box in the question section, not the answer section).

To remove the sort by votes, you can add the following code to the custom CSS:
.dwqa-sort-by { display: none;}
About the comment box, I have checked and see that it removed, you can send me a screenshot for further checking.

here is a screen shot:

regarding the sorting, i want to keep the sort by views and sort by answers, but hide the sort by votes. is that possible?

I have checked and I see that it’s cache site, please clear cache your site and check it, If you want to remove the vote in the Sortby section, you can open the archive-question-filter.php file and remove the line 35.

the cache is off in my site (and was off for a long time). is there another way to fix this issue?

You can create a dwqa-templates folder in your theme folder and copy/paste the comments.php file from DW Q&A plugin to this folder and remove the following code:
<pre><div class="dwqa-comments">
<?php do_action( 'dwqa_before_comments' ) ?>
<div class="dwqa-comments-list">
<?php do_action( 'dwqa_before_comments_list' ); ?>
<?php if ( have_comments() ) : ?>
<?php wp_list_comments( array( 'callback' => 'dwqa_question_comment_callback' ) ); ?>
<?php endif; ?>
<?php do_action( 'dqwa_after_comments_list' ); ?>
</div>
<?php if ( ! dwqa_is_closed( get_the_ID() ) && dwqa_current_user_can( 'post_comment' ) ) : ?>
<?php
$args = array(
'id_form' => 'comment_form_' . get_the_ID(),
);
?>
<?php dwqa_comment_form( $args ); ?>
<?php endif; ?>
<?php do_action( 'dwqa_after_comments' ); ?>
</div></pre>

can you explain a bit more on how to do this step:

1. what is the location of the theme folder?
2. what is the location of the comments.php file

suddenly i have a problem that the comments don’t appear at all in desktop view (not in the question section, and not in the answer section). is there anyway to fix this also?

Go to your theme folder (wp-content/themes/[theme-name]), and create a new folder, named it “dwqa-templates”. Inside your new folder, create a new file: “comments.php” and paste the following code to the comments.php file:

<?php
/**
* The template for displaying comments form
*
* @package DW Question & Answer
* @since DW Question & Answer 1.4.3
*/
?>

<?php if ( comments_open() ) : ?>
<div class="dwqa-comments demo-comment">

</div>
<?php endif; ?>
