Blank screen on some FB menus

A

AC Question

Using the Facebook App on 2 identical tablets (HP Slate 7 plus).

Tablet 1: Search bar is across the top, then underneath are the 5 icons (home, friend requests, chat, statuses, menu).
Tablet 2: Search bar and the 5 icons are all across the top.

Tablet 2: selecting the menu (3 horizontal bars), then selecting 'find friends' presents a blank screen.

Tablet 2: selecting any FB post that contains a long post and includes a selection to 'continue reading', also presents a blank page.

I have already tried to un-install app and re-install, but the same issue continues.

Please help.
