From the CLI:

  • Run the command php bin/theme to see the available themes.
  • Use the same command with the argument name (php bin/theme <THEME-NAME>) to choose a theme.
  • If you want to revert back to the original bootstrap theme, run the command php bin/theme default.

Clear the browser cache once you have applied.

Change app install name

Add to the config.php file an array element like this:

return array(
    'app_name' => 'This line will overwrite "XBackBone"',

ShareX Configuration

Once you are logged in, just go in your profile settings and download the ShareX config file for your account.

Linux Support

Since ShareX does not support Linux, XBackBone can generate a script that allows you to share an item from any tool:

  • Login into your account
  • Navigate to your profile and download the Linux script for your account.
  • Place the script where you want (ex. in your user home: /home/<username>).
  • Add execution permissions (chmod +x
  • Run the script for the first time to create the desktop entry: ./ -desktop-entry.

Now, to upload a media, just use the right click on the file > "Open with ..." > search XBackBone Uploader (XXX) in the app list. You can use this feature in combination with tools like Flameshot, just use the "Open with ..." button once you have done the screenshot.

The script requires xclip, curl, and notify-send.

Note: XXX is the username of your XBackBone account.

Web server configuration notes

If you do not use Apache, or the Apache .htaccess is not enabled, set your web server so that the static/ folder is the only one accessible from the outside, otherwise even private uploads and logs will be accessible!

You can find an example configuration nginx.conf in the project repository.

Maintenance Mode

Maintenance mode is automatically enabled during an upgrade using the upgrade manager. You can activate it manually by adding in the configuration file this:

return array(
    'maintenance' => true,
