Recently updated the addon, now the arena frames are not showing. What could be the reason?

What wow version is that?

Updated to 2.7.2, works, thanks!

3.4.3

I installed the previous version of the addon (2.6.4) and the arena frames are working again.

So 2.7 breaks it too, not only 2.7.1?

I dont know, I can't install 2.7 using curseforge. Prev available version is 2.6.4. I guess 2.7 works fine, because i update addons almost every day and the problem appeared a few days ago.

Ah, I think 2.7 wasn't tagged as available for wrath, only for retail. This is still manual....

I pushed 2.7.2 just now, I hope that fixes it.
