Not working :\
I know that I can wipe and re-flash the ROM, but I think that pinpointing the problem and bringing it to the attention of the community helps prevent it from occuring in the future. Just a hunch
I may be mistaken, but long pressing on a toggle should open up the settings menu for that option (wifi opens wifi settings, for example). It is highly unlikely that the devs would program two conflicting long-press actions, so my guess is that you are mistaken - there was no drag and drop. A previous user mentioned a button on the drop-down that hides (or unhides) the toggles, but that is an all-or-nothing sort of function - a single toggle would not be affected.
Explore the settings (I can't remember where the power widget toggle options are in AOKP, maybe under rom control?) - there is a menu that allows you to choose which toggles are available, and I'd bet that your missing toggle was turned off... unless you're looking for the 4G toggle (I need to re read your original post, can't remember if you specified) - the latest AOKP that I tried (two days ago) still lacked the 4G toggle on the pull-down, so the only quick method is a widget that can be placed on the home screen.
EDIT: I re-read your original post - if you are missing
all of the toggles, pull down the status bar drop-down, and click the settings icon (some themes may change it, but the stock icon depicts three sliders, blue on a black background) to unhide them again.
