That isn't the most common, but it's my favorite.
Your instead of you're for you are. There instead of their when referring to someone. To instead of too when you mean also. Its when you mean it's as in it is and visa versa.
BTW, I think the reason why you see referer instead of referrer is because the header variable is HTTP_REFERER.
They call it a "play on words" but that's face-saving for misspelling in the first place:

There are no apostrophes there! Apostrophes are used for possessives—like "He stepped on the cat's tail." or "The car's tailpipe fell off." But not for plurals! Never for plurals!
I swear, some people must feel compelled to put apostrophes on any word that has an "s" at the ending: See how great thi's look's? Yeah, I love them apostrophe's!
My personal pet peeve is the inappropriate use of apostrophes. "There are too many cat's." "The car's were going too fast."
I hate when People randomly Capitalize Words. There is no Reason to do so, yet I See it Daily.
Also, I'd say a common error is 'who' when it should be 'whom', since most people don't know that rule. Also, you gotta love when someone tries to correct your "grammer". ;-)
