Nostalrius Begins - Quality wow vanilla realm (1.12)

To put it short, I have an issue with my blizzard playerframe being unable to be disabled in every unitframe addon i have even if it has the option, and my Questie is randomly starting to give me this error when I try to re-enable it in the map while it gives me a ton of unmarked quests in it's log and when I disable them it gives me another error alongside one when i start loading into my character, does anyone know how to help me with this? I've tried reinstalling WoW, all my addons, clearing the cache and WTF folders, swapping enGB to enUS and back, nothing has worked so far.

Questie pops up same error for me from time to time, just use http://addons.us.to/addon/improvederrorframe so it won't bother you (that erorr doesn't really break anything).
Also, get the newest version from here, if you don't have it: https://github.com/AeroScripts/QuestieD ... master.zip

Is there another problem with questie? Might be related to other addons you're using, you can try disabling some of them to see if it helps. Also you can look for different versions of same addons in my site (link in signature).

What do you mean with "blizzard playerframe being unable to be disabled in every unitframe addon i have even if it has the option"? If you use some other unitframe addon, you can't see your playerframe at all? (I mean, you can't see both - neither new one that is provided by unitframe addon, nor old one - blizzard default playerframe?)
