Hello/Bonjour, (french below)

After installation (or rather after clicking on install) I have this error message :

Fatal error: Uncaught Error: mysqli object is already closed in /include/dblayer/functions_mysqli.inc.php:88 Stack trace: #0
/include/dblayer/functions_mysqli.inc.php(88): mysqli->set_charset('utf8') #1 /install.php(261): pwg_db_check_charset() #2 {main} thrown in /include/dblayer/functions_mysqli.inc.php on line 88

I looked at the functions_mysqli.inc.php and install.php files and apart from seeing that lines 88 and 261 as described in the error message I have no idea what to do...
Can anyone help me please?

Après installation (ou plutôt après avoir cliqué sur installer) j'ai cette erreur :

Fatal error: Uncaught Error: mysqli object is already closed in /include/dblayer/functions_mysqli.inc.php:88 Stack trace: #0
/include/dblayer/functions_mysqli.inc.php(88): mysqli->set_charset('utf8') #1 /install.php(261): pwg_db_check_charset() #2 {main} thrown in /include/dblayer/functions_mysqli.inc.php on line 88

J'ai regardé les fichiers functions_mysqli.inc.php et install.php et à part voir que les lignes 88 et 261 comme décrites dans le message d'erreur je ne sais pas du tout quoi faire...
Quelqu'un peut-il m'aider s'il vous plaît ?
