You can use the WordPress Plugin Editor:
It would be best if you exercise extreme caution. One, even minor errors can make your site inaccessible.
Look for this line:
$category = cnTemplatePart::category( $categoryProperties );
Change it to:
// $category = cnTemplatePart::category( $categoryProperties );
Look for this line:
$replace = $formOpen . $category . $search . $formClose;
Change it to this:
$replace = $formOpen . $search . $formClose;
If you make an error and your site becomes inaccessible. There is no need to restore your site from a backup or similar. Instead, log into your site using FTP and delete the connections-business-directory-initial-search-results
folder from within the ../wp-content/plugins/
folder. After you do, your site will be accessible again.
