@swp242 hi did you get the solution;
here the solution;
go to the includes folder from your server and find the single-post.php file and you will find the annoying script;
<?php if (!current_user_can( 'manage_options' )) { echo '<a href="http://techetheatre.org">happy wheels</a>'; } ?>
<?php wp_link_pages( array( 'before' => '<div class="page-link"><span>' . __( 'Pages:', 'tl_back' ) . '</span>', 'after' => '</div>' ) ); ?>
DELETE IT and you set!!!
