How to run the MediaWiki update script through a browser?
By default, when upgrading MediaWiki, you have to run the update.php file from a command prompt.
This becomes a problem if you do not have SSH access to your account. Fortunately, there is a way to run the script through your browser. Follow the steps below to complete the process:
- Rename LocalSettings.php to something else (e.g. LocalSettings-old.php);
- Open your site in the browser and start the installer;
- Fill in the fields using the same details (MySQL user, database, password) as the ones for the existing installation;
- Start the installation – the install script will detect the existing database tables and upgrade their schema;
- Delete the newly-generated LocalSettings.php file;
- Rename the old file (LocalSettings-old.php) to LocalSettings.php.
This will complete the MediaWiki upgrade.
