Guide: fix to infinite loading screens
I got response from ESO support about my infinite loading screens.
Hope this works for you, it worked for me. Now, I don`t have this issue anymore.
Open: \Documents\Elder Scrolls Online\live\SavedVariables, and delete "ingame.lua" and restart the game
My "ingame.lua" was "ZO_ingame.lua" so.....Its also that.
