And looks there’s a bug here and it’s very easy to repro:

1. on home page, click to any category to navigate to the category page
2. click the top logo to go to home page, and you can still see the topics of excluded categories

and on IE, get an error saying /latest.json?exclude\_category=category1:category2 cannot be loaded because of internal server error, but there’s no error log in admin logs.

(and when you refresh the page, the topics will be loaded correctly again)

```plaintext
服务器错误

无法载入 /latest.json?exclude_category=category1:category2 

错误代码：500 Internal Server Error 

返回 再试一次 

```

hope someone could fix this. @codinghorror
