Forum Strange problem
 

Hi,
I have strange problem, for long threads in a forum thread view I should see links to first 3 pages ... and link to last page ie. 1,2,3...46

Some of my users can't see this last post link, as they say it's all white, the same as background.
I checked it on chrome, IE and FF, and all looks fine.

They see:

Any idea what could be the problem, if I'd have info about it from one users I'd think it's something wrong with his comp/browser. But now I know that at least 4 users have the same issue.
