Error: "Impossible to load class id" - by: numand

Hi,
As a local non-government organization, I am trying to evaluate how ProjeQtOr will meet our expectations. I installed ProjeQtOr version 8.2.3 to our server which runs Ubuntu 16.04.6 LTS as follows;

1. Install required packages:

2. Configure MariaDB:

3. Create DB user and db:

4. Configure php.ini





5. Configure nginx:

6. Make server root directory, change ownership and extract zip file:

7. Restart services and run installation


After all these prerequisite steps, I start installation by typing localhost to web browser. I changed default DB user as "projeci" and default DB user password to "something". Installation went flawless but when I try to login as user "admin" with password "admin", it throws an error:


When I inspected to problem, I found these lines in ..projeqtor/files/logs/projeqtor_20191105.log:


And this function from projeqtor/model/persistence/SqlElement.php is where the error occured (the last line is 3059.nth line)


There is no id.php file in projeqtor directory. So, why it is looking for it? Could you help me to solve this problem?

P.S.: My native language is not English.
