In this series of articles, I am going to introduce each of the plugins I have developed for ClassicPress, a hard-fork of WordPress, which was originally created to provide an alternative, yet compatible, CMS without the Gutenberg block editor.
The 26th plugin is Maintenance Mode.
Enable maintenance mode to disable the front-end of your ClassicPress site for non-administrators.
Users will only see the configured message; administrators will have full access to the site, but a prominent configurable warning that maintenance mode is enabled will be displayed at the top of every page.
This plugin is multisite compatible with each site having its own settings.
