I'm a bit new to wordpress and php and I'm trying to create a site where users have the possibility to change the appearance of the index page for other visitors. This could perhaps be done with back-end access to a maintenance plugin but I want it to be more simple than that for the user. Basically just log in and then push a button to open the site.
What would be the best way to achieve this?
#Plugin name 'Name' => 'Maintenance Mode',
#Author of the plugin 'Author' => 'Michael Wöhrer',
#Authot URI 'AuthorURI' => 'http://sw-guide.de/',
#Plugin URI 'PluginURI' => 'http://sw-guide.de/wordpress/plugins/maintenance-mode/',
#Support URI: E.g. WP or plugin forum, wordpress.org tags, etc. 'SupportURI' => 'http://wordpress.org/tags/maintenance-mode',
#Name of the options for the options database table 'OptionName' => 'plugin_maintenance-mode',
