Hello,
I have been trying to use the api for some time, but I cant' get past this error:

{"error":"invalid API query", "message":""user 'projeqtor' unknown in database""}

The php file used to make the request:

The .htaccess file located in WEBROOT/projeqtor/api/ :

  RewriteEngine On

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?uri=$1


Here's an extract from projeqtor parameters.php file:
<?php
$paramDbType='mysql';
$paramDbHost='127.0.0.1';
$paramDbPort='3306';
$paramDbUser='projeqtor';
$paramDbPassword='PASSWORD';
$paramDbName='projeqtor';

AuthUserFile WEBROOT/projeqtor/api/.htpasswd

AuthName "ProjeQtOr"

AuthType Basic

Require user projeqtor
So far I have checked:

- that the .htaccess file is correctly used by apache

- that projeqtor exists as a user in mariadb and has all required privileges on the database

- that the database was up and running

- that the modules auth_basic and rewrite were installed and enabled

- that the .htpasswd was where it needed to be with the right infos in it (generated via htpasswd command)
I am running out of ideas and would really appreciate if someone could figure out what is wrong.
