To check for this, please search the generated HTML source of the page with the table (accessible via the “View Source” feature in the browser) for the string “jquery”. If there’s more than one result within HTML
<script> tags, this means that the library is loaded multiple times. If that is the case, the loading of the old versions should be stopped, so that only the version that comes with WordPress is loaded. This usually means deleting a line similar to
from the theme’s “header.php” file. Other variants are lines like
wp_deregister_script( 'jquery' ); wp_register_script( 'jquery', ... );
in the “functions.php”.
