Your use of `printf` and `__` is somewhat confused, instead of:

````
<?php printf( __( '<strong>%s</strong>', 'wpremote' ), 'WP Remote is almost ready' ); ?>, <?php printf( __( '<label style="vertical-align: baseline;" for="wpr_api_key">%s</label>', 'wpremote' ), 'enter your API Key to continue' ); ?>
````

Should be

````
<strong><?php _e( 'WP Remote is almost ready', 'wpremote' ); ?></strong>, <label style="vertical-align: baseline;" for="wpr_api_key"><?php _e( 'enter your API Key to continue', 'wpremote' ); ?></label>
````
