Dont know wht this frame is... :(
 

I was making some changes in my UI and just after /rl this vertical pink and blue bar appears in the middle of the screen... Someone can pls tell me wht is it and how to quit it from there?

Screenshot of the bar:

What unit frame addon are you using? If you're using discord unit frames, it looks like the XP bar is set to vertical.

I use AG unitframes...

Edit:

Found it!! was Xparky... thanks Dreadlorde you gave me the hint! ;)
