[BUG] Searching for items broken (Cata Classic)

[volostyle]

I'm on version 3.11.0. Whenever I search for an item in my bags, the search function doesn't work, and I get the following Lua error:

173x ...s/Blizzard_ItemButton/Classic/ItemButtonTemplate.lua:231: attempt to index global 'ItemButtonConstants' (a nil value) [string "@Blizzard_ItemButton/Classic/ItemButtonTemplate.lua"]:231: in function GetItemContextOverlayMode' [string "@Blizzard_ItemButton/Classic/ItemButtonTemplate.lua"]:245: in function UpdateItemContextOverlay' [string "@Blizzard_ItemButton/Classic/ItemButtonTemplate.lua"]:212: in function UpdateItemContextMatching' [string "@Blizzard_ItemButton/Classic/ItemButtonTemplate.lua"]:165: in function <...s/Blizzard_ItemButton/Classic/ItemButtonTemplate.lua:164> [string "=[C]"]: ?
