Is this a bug or what is the issue ? Security ? To solve this I need change passoword on my database and which files on qlo and/or qlo database. Thx

@maurice Hi.

Please contact your hosting provider regarding database connection issues.

QloApps stores database credentials in file: qloapps_root_dir/config/settings.inc.php

Be cautious while editing this file because it may cause irrecoverable loss.

@akr Thx. It is a security issue and I havent found where an how. It has happened to me two times in 6 months. I have recovered systems just creating the database user again on server and assigning to qlo databases again according to /config/settings.inc.php. Have changed passwords & users on databases and Cpanel but happened again. I just wanted to know if someone else had this issue. Thx again.
