The action is update_option_permalink_structure. You get the old and the new value as parameters. add_action( 'update_option_permalink_structure' , 'my_custom_function', 10, 2 ); function my_custom_function( $oldvalue, $_newvalue ) { // do something } There are also the actions update_option_category_base and update_option_tag_base.
