MantisBT theme which switches between light and dark modes in the day and at night, respectively.
Upload the whole folder into your plugins/
folder in the mantis installation so that you e.g. have MANTIS_INSTALLATION/plugins/mantisbtAutoSwitchTheme/mantisbtAutoSwitchTheme.php
. After that the plugin should show up on the manage_plugin_page.php
page in the mantis settings. There you can simply install it to activate it.
Then each user can activate it from their Account > Preferences.
