Add Polylang support for Customizer This plugin adds Polylang support for WordPress Customizer. Support We provide direct support via our Frontbee Discord server Features Language switcher in Customizer. Localized theme_mods and options for both default and custom made Customizer values. Enable/disable forcing “The language is set from content” setting in Language->Settings->URL modifications Prerequisite Polylang must be installed and activated. Languages must be set in Admin > Languages. If you have a static front page: Create a front page per each language. Select the front page in Admin > Settings > Reading per language. Expect customizer to use setting type = theme_mod (default) as in: $wp_customize->add_setting( ‘setting_id’, [ ‘type’ => ‘theme_mod’, ] ); License This plugin is licensed under the GPL v2 or later.
