Sorry, your application is offline.

Error message

Sorry, your application is offline.

What it means

When MAIN_ONLY_LOGIN_ALLOWED is set, Dolibarr restricts access to only the listed logins (maintenance mode). This branch fires when there is no logged-in session at all (or the login check otherwise left $ok=0): the visitor is told the app is offline and that only the listed administrators may connect for the moment.

Solutions

1. Remove or empty MAIN_ONLY_LOGIN_ALLOWED in Home > Setup > Other Setup (or conf.php) once maintenance is over
2. Log in as one of the allowed admin logins listed in the message
3. Wait/retry later if maintenance is intentional

// check before deploy: SELECT value FROM llx_const WHERE name='MAIN_ONLY_LOGIN_ALLOWED';

When it happens

Trigger: MAIN_ONLY_LOGIN_ALLOWED global (e.g. 'admin') set in setup or conf.php; an anonymous visitor hits any page requiring main.inc.php, so session has no dol_login and $ok stays 0.

Common situations: Admin enabled maintenance mode after an upgrade and left it on; a user hit the site during a migration window; staging copies of production conf with the restriction still enabled.
