Chat box disappeared from fb?

[RELAINNE ROBYN]

That whole thing on the right of my face book home page is gone. Even the small notifier on the top of the chat box. Then i can't properly upload images, i had to use the basic up loader. Then i can't comment properly or post properly. Then i can't go to facebook.com/messages/ because it's blank and i can't see who left me messages. Notifications won't load also. I also can't search profiles or message anyone properly. Google is updated, Adobe is updated. My wifi signal is slow, does it have any connection to this at all? What should i do to get face book running properly again?
Im using Google Chrome, it's updated. So is my Adobe flash player. Also chat box is still not present even when i took out all of my ad blocking extensions. I did the same with my other browsers, Mozilla Firefox and Internet Browser. Which was hard to do since removing extensions slowed my internet/wifi connection even more. What should i do now? i restarted google chrome, it's still not present.
