Which addon is EsoUI?
An in-game error, a load-order warning or a red Dependency line that mentions
user:/AddOns/EsoUI/ — or a folder sitting in your
Documents\Elder Scrolls Online\live\AddOns\ that you do not recognise — belongs to what
is listed below.
Anchors for every claim on this page: the live game runs API 101051 (Update 51, live 2026-09-28). Update 51 went live on PC/Mac on September 28, 2026. Feed retrieved 2026-10-06 · corpus snapshot 2026-09-28.
12 addons in the ESOUI catalogue ship a folder called EsoUI, so the folder name alone does not settle it. The standalone one — the copy its own author publishes and updates — is EsoBR - Tradução Português - v2026; the others bundle a copy of it inside their own download. The game loads exactly one folder of a given name.

How to read the error line
An ESO Lua error is written as
user:/AddOns/<Folder>/<File>.lua:<line>. Only the
<Folder> segment identifies the addon — the file name and the line number are internal to it,
and the addon's display name in the add-on list is frequently different from its folder name. That is the
whole reason this page exists.
