error related to rate_post and current_rating

Good day. I followed the instructions and installed the plugin. Added the code “<?php if(function_exists(‘the_ratings’)) { the_ratings(); } ?>” to the template. I went to the site and saw this error “(index):390 Uncaught ReferenceError: rate_post is not defined
at HTMLImageElement.onclick”. Please tell me how can I solve her problem?
