Broken Page Number Entering Thing

This is a somewhat minor issue, but it is annoying. Ever since the forum upgrade, the thing that allows you to manually type in the page number you want to view of something - in the member list, the blogs, or the forums - is broken. 
 

 
That thing. In topics it still works...but in a forum, I get this...
 

 
The forum is set to the default viewing settings, so confused...
 
On the blogs, the use of said feature just brings me back to the first page of the blog, not the page I typed in. 
 
And the member list...
 

 
 This happens regardless of the number I type in these instances. 
 
Manually navigating between pages - clicking the numbers on the top of the screen or the arrows or the "NEXT" button still works, it's just the manual type-in that's defunct.
