I am having problems with seeing my item level, i have the newest version updated, and i see xxx for my item level as well as others, my friend has the same problem, here is a screen shot.    http://imgur.com/zE0mmGs

do you have TipTac installed?

if that's not it, try disabling all addons except oQueue and log back in to see if it works

no i don't have that addon, i did logout of the wow interface entirely then logged back in and i can now see my item level, over time when i am in raids and been playing for a while it tends to do that to the item levels and says xxx, not sure why.

Im curious if you also use ElvUI...this is what happens to me intermittently as well.

The errors are posted here http://solidice.com/thread/1a2

the gear info comes in waves.  it's caching from the server.  if, for some reason, the data doesn't make it or the tooltip doesn't yield the correct info, it'll end up being xxx

no i don't use that add on.

have you tried disabling all addons except oQueue and see if it works?  if so, there is a conflict with one of your addons

that issue is not related to oqueue, i've disabled everything but a few and oqueue included. and that never happens. Im still trying to narrow it down, but with just oqueue and basic pvp addons. it doesnt happen. 

I'm getting the same intermittently - Swatter report below:
(I'd just swapped between my DPS and PvP gear at the time)

I had the same issue on two computers using oQueue.  I removed all of my addons except oQueue and still had the lua errors and xxx's in my char window.  

I was able to fix this by deleting everything that started with oqueue in my WTF folder.  I left the addon alone in the interface folder.  Checked with both all addons disabled and re-enabled.  Works good now.
