Line 72 of js.js prevents users from clicking stars if they already voted.

I cannot reproduce the problem. What you describe seems to me like a JavaScript type conversion problem:

(“true” == “true”) == true
(“false” == “true”) == false
(true == “true”) == false
(false == “true”) == false

eval(“true”) == true
eval(true) == true

alert(“true”) // shows true
alert(true) // shows true

If disable is true (boolean) instead of 'true' (String) the expression disable == "true" will return false and therefore fail.

So far this seems to be comprehensible, but kksr_ajax (index.php) always sends strings, not booleans. Additionally, there should not be a difference between visitors and registered users.

I personally would not use eval but rather a simple String (performance comparison):

(String(“true”) == “true”) == true
(String(“false”) == “true”) == false
(String(true) == “true”) == true
(String(false) == “true”) == false

You might want to change

if(eval(disable))

to

if(String(disable) == ‘true’)

IP addresses are stored in the postmeta table (wp_postmeta by default).

The following MySQL statement deletes all IP records, thus it allows visitors to vote again on all posts:
DELETE FROM wordpress.wp_postmeta WHERE wp_postmeta.meta_key = '_kksr_ips';
You may need to replace wordpress with your database name and wp_postmeta with the name of your postmeta table (table name prefix + postmeta).

To reset IP records of a single post you can use this statement:
DELETE FROM wordpress.wp_postmeta WHERE wp_postmeta.meta_key = '_kksr_ips' AND wp_postmeta.post_id = '999';
where 999 is the post id.
