I search any solution of this particular bug but when I search "newsfeed" in search box, don't find a reason to this bug.

Ok, the problem that I see is this one... 

When any newsfeed have a lot of comments, the count fails and any times don't show the option --> "+4 comments". by default, the system show 3 comments and look this printscreen....

To try solve this problem, first I try to change the comments showed by default and I put 5 but this option fails with count of comments.

For example.. in one newsfeed there are 7 comments (5 showed) and don't put any more (must be showed: "+2 comments")

In other newsfeed there are 17 comments and the system show the button: "+7 comments" and when you press show all comments but the count option fails.

The script clearly fails on the right button and when account it's 0 or negative don't show the option to show more coments.... 

Where is the part of script that I can solve this error???
