Translate fields

Hi,
I’m trying to translate the fiels. I’m currently using polylang.
Here is what I did:
1. Replace the
<?php echo $imgvisit ?> Visit Today : <?php echo $pengunjung ?>

By:
<?php echo $imgvisit .pll__('Visit Today', 'mechanic-visitor-counter') .$pengunjung ?>

2. Added the following line at the top:
`pll_register_string(‘mechanic-visitor-counter’, ‘Visit Today’);

But looks like new entries don’t appear…

Is having a multi lingual version of this plugin something you would consider?

thank you ??
