In the Astra Pro v2.5.1, we have added two new filters to update the Read Time text – specific to Minute & Minutes of reading text for Blog & Single post page.
You can use the below filters to modify the Read Time strings –
For updating the Singular Read Time –
add_filter( 'astra_post_minute_of_reading_text', 'ast_post_minute_of_reading_text_function' );
function ast_post_minute_of_reading_text_function() {
return __( 'Singular reading time...', 'astra-addon' );
}
For updating the Plural Read Time –
add_filter( 'astra_post_minutes_of_reading_text', 'ast_post_minutes_of_reading_text_function' );
function ast_post_minutes_of_reading_text_function() {
return __( 'Plural reading time...', 'astra-addon' );
}
