When I open the friends window and go to the Quick Join tab, I get LUA errors.
I have tried disabling all of my addons and clearing my Cache.
In the capture below you will see ‘Cryptids#1505’, who is the leader of a community, of which I am a member.

You’re certainly not alone. I’ve seen a number of people mentioning this, and see it semi often myself.
If you look at the formatting of the quick join tab… it looks real messy, and broken.
Last time I saw it I disabled all my addons and reload the ui; no more error.
I then enabled one addon at a time until I was back to what I had when I got the error… and nothing. Reloaded the UI a few more times; no errors. Relogged; no errors when joining.
It’s an odd one, but I have a feeling it may be more of a blizzard issue than some addon creating the issues… but who knows; I just know the only addon elements I see in these errors are 100% Blizzard.
The one thing I did make sure to confirm was that weizPVP has nothing to do with it 
If I find anything more later I’ll post updates
