Here are the steps involved when moving a WordPress Multisite installation to a new domain name. In my case I wanted to move everything (code + database) from development to production. After copying everything to the new environment, you have to change the following items: Make sure to add or update your wp-config.php file: define('DOMAIN_CURRENT_SITE', […]

WordPress advises to use the Settings API when programming a settings page. But as you start using it, you quickly get overwhelmed with all the arguments you have to give to functions like register_setting, add_settings_section, add_settings_field, settings_fields, do_settings_sections, add_menu_page and add_submenu_page...

Unfortunately it's not possible to do this within the app itself as far as I know, but you can see it in a shell. In the below example I want to see all the alarm manager entries for my package my.package.name. The "when" field in my case is as Unix timestamp, so I rewrite it […]
