Cannot upload img on desktop

I've just discovered that I cannot upload images to comments when on desktop. However, it works fine on iPhone when I tried. I have tried on several different computers. I have another site that is also using the latest version of wpdiscuz, and upload works fine on desktop there, so clearly something is wrong with my site. I cannot figure out what.
When I check console on Chrome, I see the following error messages when I try to upload an img on desktop:
jquery.min.js:2
POST https:// www. mysite .com/wp-admin/admin-ajax.php 400 (Bad Request)
send @ jquery.min.js:2
ajax @ jquery.min.js:2
(anonymous) @ jquery-migrate.min.js:2
e.<computed> @ jquery-migrate.min.js:2
_e @ wpdiscuz-combo.min.js:10
(anonymous) @ wpdiscuz-combo.min.js:14
(anonymous) @ wpdiscuz-combo.min.js:14
dispatch @ jquery.min.js:2
v.handle @ jquery.min.js:2
c @ rocket-loader.min.js:1
wpdiscuz-combo.min.js:14
Any ideas?

Hm, it appears it was a local browser cache issue because it works fine after clearing cache. But the problem is other visitors are experiencing the same thing and not everyone will know to clear their cache. Any suggestions?

We're really sorry, but, there is no solution we can provide in this case. The wpDiscuz plugin cannot clear the local browser cache.
However, you can add a small description, such as an admin note, using the comment_main_form_after_head hook.

@asti I understand. I did not know this when I started the thread but eventually came to this conclusion.
What do you suggest I do with that hook?

You can write an admin note asking users to press CTRL+F5 if they experience any issues like this.
add_action("comment_main_form_after_head", function () {
echo "Dear users, if you come across any difficulty with uploading images, please press CTRL+F5 (to clear the browser cache) and try again. If you still have any issues, please contact the website administrator at your email@example.com.";
});
This is just an example—you can customize the red-marked text as needed.
This is not the only hook that allows you to add such a custom message. You can find all available hooks here: https://wpdiscuz.com/docs/codex/actions/
Once you review them, you can choose the one that best fits your needs.

@asti I'm curious how this could of happened? I mean, members can't upload images. Is this really normal?

This is not normal. The only possible reason for this issue is a cache problem. I'm not sure if your website visitors have ever been unable to attach a file.
I've just answered your question:

@asti yes, I am aware of all of this but I'm curious how this could have happened with this plugin particularly. It doesn't matter what I do. I can turn off all cache on the site and cloudflare as well, but the problem persists since it's now become a problem with users browser cache.
Oh well. That's life running a website I guess.

Hm, if you can tell me which js file is used to attach images maybe I can make a small edit to that file and see if it breaks browser cache. Are you able to tell me?

I don't think you'll face this kind of issue anymore, so I don't recommend you change anything.
