How to allow post requests to be sent to dle?

Question

JavaScript

Good afternoon. I wrote a loader for files with verification, etc. (not the point). When sending a post request, the following error occurs: loadfile.js:506 POST mydenwersite.ru:81/engine/modules/uploader/upload.... 403 (Forbidden).
In .htaccess, these rights are:
Order Deny,Allow
Deny from all
Ps all transferred files are uploaded to uploads, in the root of the site. This is so that they do not think that I throw all the files in the modules.

Answer 1

Here is line 506: _$$.$(formid).submit();
