Put Drupal Sites in Maintenance Mode Manually

Put your Drupal Site in Maintenance Mode Manually

Drupal allows to set a website offline with a few clicks via the admin interfacte.

However, we’ve seen situations where the admin interface becomes unavailable, often via a white screen of death.

In this tutorial, I’m going to show you a manual way to force your Drupal 7 site in maintenance mode.

Step #1. Edit the settings.php file

  • Edit the file sites/default/settings.php file, using a FTP client or through cPanel:

  • At the very end of settings.php, add the code below:

{codecitation php}$conf[‘maintenance_mode’] = 1;{/codecitation}

Step #2. End result

Your site will now display the “Site under maintenance” page:

Step #3. Put your site back online

Remove the line of code from Step 1, or change the value to 0 to put your site online again:

{codecitation php}$conf[‘maintenance_mode’] = 0;{/codecitation}

Eliminate the type of rule from Phase # 1, or modify the value to 0 to put your site online again:

Sadly, this doesn’t appear to work in Drupal 9.2.7 where I have exactly the situation you describe: a maintenance page and nothing, not even ?q=user works.

Also, if I run update (having allowed that via settings.php) when the update is finished, only the “front page” option is available  – no access to administration pages.

The recommended solution is drush but that requires SSH or editing a blob in the database.

It used to be so simple: go into the DB, change a flag from 1 to 0 and get on your way.

So much progress isn’t. 🙁

Yes – you are correct unfortunately.

Drush is definitely the way to go on any Drupal site though – it’s worth putting a site where you can use it I think (if you can)…
