Practice tactics. Easy combinations, mate in 1, in 2, in 3. That will get your tactics back on track. Other than that, if you play well below your usual level, the reason may be outside the chess board. Something causing you stress, are you really tired, maybe in love? Whatever the reason, something may keep you from focusing on the game. Relax, fix, and rule the 64!
WAKE UP!!!

Chess is something that takes place in your head. You need to work on that thing in there to improve. Perhaps you should slow down your thought processes and look at the board and try to visualize where pieces go and what they do when they get there.
Oh, I see you play a lot of live stuff. Don't play too fast.
