Moneyframe Lua errors on hover

Support Bug Report
77

This is a Lua taint error in World of Warcraft Retail’s built-in Blizzard_MoneyFrame code (specifically line 340 in MoneyFrame.lua).

It occurs when hovering over bag items (or other tooltip triggers like SetBagItem), as the game tries to display the item’s vendor sell price in the tooltip’s money frame (e.g., “4s 70c” for 470 copper).

Why it happens:

  • WoW’s UI has “secure” (protected) frames and variables to prevent exploits in combat or restricted execution (e.g., action bars).

  • Addons can taint these, turning normal values into “secret” (unreadable) ones during certain operations.

  • Here, WorldQuestTracker taints the local silverWidth variable (used to size the silver coin button in the tooltip money display).

  • When MoneyFrame_Update runs, it tries arithmetic like width = goldWidth + silverWidth + spacing but fails because silverWidth is a “secret number value” (visible as in locals, but protected).

This bug exploded around January 2026 after a patch (likely tied to the Midnight expansion), affecting tooltips even with no addons in some cases—but addons like WorldQuestTracker, Bagnon, Auctionator, etc., trigger it reliably.

Quick fixes (in order of recommendation):

  1. Update WorldQuestTracker: Download the latest from CurseForge. Recent versions (e.g., v12.0.0.547+) may have mitigations.

  2. Disable WorldQuestTracker:

    • Exit WoW, rename its folder (WorldQuestTracker → WorldQuestTracker_disabled), relaunch.

    • Test by hovering bags—if errors stop, it’s confirmed.

  3. Install a suppressor addon:

    Addon What it does Download
    PlsFixMe Tooltips (v1.0.1, Jan 26, 2026) Blocks silverWidth (and similar like textHeight, comparison tooltips) errors; fixes missing world quest/item tooltips. Temporary workaround—prices may not show in combat.

  4. Blizzard side: They’re aware (multiple forum threads), but no hotfix yet. Report yours: /console scriptErrors 1, reproduce, submit via in-game bug reporter.

Errors spam the chat but don’t crash WoW. Reload UI (/reload) after changes. If it persists without WQT, check other tooltip/quest addons (e.g., AllTheThings, Bagnon)

I ran the code through Grok and this is the response i got.
