they are not missing for me and we didn't change anything in the site layout.
it's probably a cache problem. Try that:
1) Ctrl+F5 on the page
2) if that didnt work, clear the cache of your browser, close your browser, restart it, and visit gbatemp again
3) if that didnt work either, you need to uninstall your browser and reinstall it (or create a new profile if you're in firefox)
I had to go up to the 3rd solution once as my cache was really damaged
