2 UI 

His English as he said isn't very good so what he puts out does a great job. So unless someone is helping him with translation well it's damn hard as he codes a lot as is.
Anyway the end is coming fast we won't need addons lol

yea some addons are in Chinese
like the loot manger and the UI

Nearly all is English just some chat messages appear in Chinese. I presume you were talking about the Ui.

is there a way to change the language to English?

If you installed it correctly it will be there.
Reinstall it in-game make sure it's loaded by hitting ESC key addons and has a tick in its name.
If you still can't see it means you haven't installed it properly.

Why doesn't Weak Auras show up, Its in the folder but not on the addon list

This error has been around forever. What happens when in combat the players target bar does not show up.


EDIT downloaded git version and error has gone and second one hasn't come back up but i suspect it may.

Here is a picture of what i mean with gold symbol. Maybe this is wanted maybe not i don't know

They only happen when you open the Argus map if that helps.

Well if I understood what you were asking thought you meant changing the action bar scale. The ui scale yeah you can change it and yes been using it since the start and have helped a lot of people in the process but you seem to know a lot about it so have fun.

there is a slider for action bar scale so no you dont have to know lua. and the gold symbol in the info bar top left for example ? i mean do you even use this ui or had a look at it ?

You need to know LUA to change the scale. But there are different action bar combinations in the UI. which gold symbol?
Right-click minimap click 2ui and in the action bar-style play around with it, you might find one to suit you better.

yes. i did a clean install and i tracked the error down to closing a vendor window in my case. can you change action bar scale and what does the gold symbol look like for you ?
