https://codex.wordpress.org/Installing_WordPress#Using_phpMyAdmin You have to log in with the account that holds all the privileges usually called root, look at the guide indicates 7 change permissions.
in the host field use local and not any host

everything is possible but I have no competence in this.
But if you connect from the beginning in https you can’t see http 500 error.
Use an online websniffer to verify that when you are in https there are no redirects.

From php 7.2 there is no longer mcrypt instead libsodium is used or a third-party library called sodium_compact https://make.wordpress.org/core/2019/05/17/security-in-5-2/
for optimal performance (speed of signature calculation) we recommend installing the libsodium library

When your WordPress site installs an automatic update, from version 5.2 onwards it will first check for the existence of an x-content-signature header. If one isn’t provided by our update server, your WordPress site will instead query for a filenamehere.sig file and parse it.

This method exists from wordpress 5.2, because it fails I don’t know 😀
You are not the only one with this mistake

yes but I have to understand why .. I copied your code .. It may be because it sees ifmodule RewriteEngine and RewriteBase twice.
try like this

# BEGIN WordPress

<IfModule mod_rewrite.c>
# FOrce ALL to HTTPS
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^stonesorganics\.com [NC,OR]
RewriteCond %{HTTPS} !on
RewriteRule [^/]? https://stonesorganics.com%{REQUEST_URI} [R=301,L]
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

make sure you nest properly ifmodule, if you have two open only two closed will exist.

can you create a test.php page?

<?php
print_r($_SERVER);

I need the url of this page

Redirect from http://www.forum.yourdomain.com http://forum.yourdomain.com https://www.forum.yourdomain.com
https://forum.yourdomain.com
https://www.yourdomain.com http://yourdomain.com

To https://yourdomain.com

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^yourdomain\.com [NC,OR]
RewriteCond %{HTTPS} !On
RewriteRule [^/]? https://yourdomain.com%{REQUEST_URI} [R=301,L]

Sorry 😀

Your server creates the door variable 443 or https on or 1, obviously you must have https already active on your server.

try this script if you can identify what you use for https. test.php

<?php
print_r($_SERVER);

call test.php from the browser https://yourdomain.com/test.php
The https rules will take precedence over everything, you have to put them just below RewriteBase /
If test.php gives you $_SERVER[‘HTTPS’] = ‘On’;

RewriteCond %{HTTPS} !On [OR]
RewriteCond %{HTTP_HOST} !^yourdomain\.com [NC]
RewriteRule [^/]? https://yourdomain.com%{REQUEST_URI} [R=301,L]

Valid for forwarding on a single domain does not use the variable HTTP_HOST simply use your domain, also to control the domain use your domain otherwise even the domains of fourth level are valid example http://www.forum.yourdomain.com or http://forum.yourdomain.com 🙂
