Pagination bug active in datatables

[alfianchii]

There are two datatables: simple datatable and datatable with JQuery.

First, simple datatable. In first load the datatable looks fine.

But when I changed the number of entries per page, the pagination (active) became weird. For example, I would like to change from 3 to 10 entries per page:

As you notice, the pagination background becomes gray (not blue).

This problem was solved by moving to another pagination. But it's kinda cumbersome and doesn't looks good to have to do this I guess ...

Second, datatable with JQuery. Where is the 'active' page? I mean, I don't know which page I'm currently on (except by looking at "Showing 11 to 20 of 26 entries" and I know it's on the second page, but it's still a pain).
