However, when I tried to use both at the same time, the sArena frame is not showing up at all. I can see the sArena configration menu appears on Esc - Interface - Addons but the frame never showed up even when I pressed the test button.
When I check the sArena.toc, I found dependencies on Blizzard_ArenaUI. I tried to delete/modify it to ElvUI but non of my methods worked. If it is convenient, may I ask how to modify the sArena so that it can work together with ElvUI? Thanks in advance!
Thanks NoM0Re! By disabling the arena frame and skining, I can see the sArena frame now! I guess it was because the sArena is a modification of the original Blizzard arena frame. When I use ElvUI frame, the blizzard frame is disabled and therefore I cannot see the sArena at the same time. Much appreciated for your help!
