you can edit at /themes/the-wp/inc/template-tags.php line 296.
<div class=”site-info”>
<?php printf( __( ”, ‘the-wp’ ), ‘WordPress’ ); ?>
<span class=”sep”></span>
<?php printf(
__( ”, ‘the-wp’ ),
__(”, ‘the-wp’),
”.__(”, ‘the-wp’ ).” ); ?>
</div>
but if you want to remove it, better you can make some donations or upgrade to pro version. Unfortunately, pro version will be reade 33 days from now 🙁
