If your WoW Anniversary XP/reputation boost isn't working, the fix is almost always simple: you must be inside the active event window and below max level for the buff to do anything, and a quick relog usually re-applies it if it silently dropped. Confirm the event is live, check your buff bar, then reload your UI or log out and back in before assuming it's broken.

  • Check the event is active — the Anniversary bonus only exists while the event is running. Outside that window there's no buff to get.
  • Confirm you're below max level — a bonus-experience buff does nothing at cap. Rep gains still apply, XP won't.
  • Look at your buff bar — hover the icons and confirm the Anniversary buff is actually present, not just assumed.
  • Relog or /reload — the fastest fix for a buff that fell off or failed to apply on login.
  • Rule out the UI — disable addons and reset your interface; a broken buff-frame addon can hide a buff that's really there.
  • Clear the cache — delete the Cache folder in your WoW install, then restart the client.

Why does my Anniversary XP boost show no bonus?

The most common reason is level. Bonus-experience buffs give you nothing once you hit the current expansion's cap, so a max-level character sees "no effect" even though the buff icon is there. Rolling a lower alt, or watching the rested/quest XP numbers on a sub-cap character, will show the boost is working.

The second reason is content type. Some bonuses behave differently in instanced PvP or specific zones, so test it on open-world mobs or quests where the XP tick is easy to read.

The buff icon is missing entirely — what now?

Start with a full relog, not just a zone change. If it's still gone, disable your addons and reload; a buff-frame or aura addon is the usual culprit for a hidden icon. If nothing brings it back, verify the event is genuinely live on your realm's schedule — event timers can differ slightly by region.

Do Anniversary boosts stack with heirlooms and other XP buffs?

Generally multiple experience bonuses add together rather than cancel out, so heirlooms plus an event buff should level you faster than either alone. If your XP per kill looks flat, that points back to being at max level or the event not actually being active — not to the buffs conflicting.

If you've tried all of the above and it still won't apply, a client repair through the Battle.net app catches corrupted files that a cache wipe misses.
