Try to delete keywords category and keywords got "An error has occured"

After looking through the code found 2 problems from op.UserDefaultKeywords.php

$categoryid = intval($_POST["categoryid"]) should be $categoryid = intval($_GET["categoryid"]);

here is the patch

< $categoryid = intval($_POST["categoryid"]);
---
> $categoryid = intval($_GET["categoryid"]);
