[SOLVED] Error installation

Hi,
First, sorry for my approximativ english...
I try to install projeqtor on our server.
PHP version is : 8.0.10 run with fastcgi Apache.
My site runs under wordpress.
In the principal directory, I have some directories like ".ssh", "wordpress-backup", "wp toolkit", ....and "httpdocs".
In "httpdocs," I have a directory "wordrpess". Under "wordpress", I have some directories.

So :
1) I create a database : mysite_projeqtor (MariaDB) SQL, ann a new user for this db.
2) I create a directory "projeqtor" under the directory "wordpess".
to follow the security tips,
3) I create a directory "project" under the principal directory (near httpdocs)
4) under this directory 'project", I put the directories "logs", "config", "cron", "attach"

5) I go to "mysite/projeqtor".
6) parameters of db (ok)
7) Directory to store Attachments : project/attach/
so on
Log file name : project/logs/projeqtor_${date}.log
all is ok
next page :
*** ERROR ****
parameter file not found at 'projet/config/parameters.php'
Check file '/tool/parametersLocation.php' or remove it to use '/tool/parameters.php'.
If problem persists, you may get some help at the forum.

I checked, and I see that the installation create a directory "project" under "httpdoc/wordpress/projeqtor/projeqt/attach (and log and config)

I am not a specialist, I don't undertstand the error.

If I install without change the directory (also installation for test -but not secured-) all run perfectly

Thank you for your help,
