Common Display Issues
Often times after a patch, user interface (UI) files can become corrupt or out-dated. These issues most commonly affect custom AddOns or modifications (such as QuestHelper, Bartender, etc). Without clearing out these "old" custom UI files, one may encounter major display issues such as items "disappearing," not being able to see in-game chat, being unable to whisper other players, and many other unpleasant situations.
While simply disabling or updating your AddOns may resolve these discrepancies, the only means by which to guarantee that a given issue is not being caused by the UI is to fully reset it.
With the game closed please try moving or deleting your WTF, Cache, and Interface folders out of your World of Warcraft directory. These are temporary files that will be recreated by the game the next time you launch. Moving them to the desktop makes it easy to replace them if necessary.
Step by step guides for your operating system can be found below.

-Click the Start button, select Programs, select Accessories and select Windows Explorer.
-In the new window click the + beside the My Computer option, this should expand a list.
-Click the + beside the Hard Disk with the (C:) label on the end (Or whichever Hard Disk the game was installed on).
-Click the + beside Program Files.
-Scroll down until you find World of Warcraft in the list and double click it.
-In the panel on the right there should be a list of files and folders, the WTF, CACHE, and INTERFACE folders should be in this list.
-Single click one of those folders and it should become highlighted, once that folder is highlighted press the Delete key on your keyboard. Do this for all three folders.
-Once the three folders have been deleted you can close Windows Explorer.
-Start the game again using the World of Warcraft Launcher to see if this helps resolve your issue.

- If the UAC is enabled, which it is by default, then the system will also be caching these three folders.
