Incorrect plugin work

Hello Error in your plugin: Your plugin show: WARNING: Found echo get_theme_mod in file_name. Theme options must be escaped (Opens in a new window). . BUT, for setting definition WP have special check algorithm, as example below for define “ display_excerpt_or_full_post ” settings, WP use “ sanitize_callback ” function: $wp_customize->add_setting( 'display_excerpt_or_full_post', array( 'capability' => 'edit_theme_options', 'default' => 'excerpt', 'sanitize_callback' => static function( $value ) { return 'excerpt' === $value || 'full' === $value ? $value : 'excerpt'; }, ) ); so as result we need define sanitize_callback function and also add same check for by pass your plugin check
