Error when using Zygor

[suman]

I have had this for several months now! The screenshot explains it all. If you have any questions about this error, please let me know. This is a daily quest ATM and I can reproduce it once a day. I am running on a Mac 2011 (MBP) with Mavericks latest release, and I am running the latest version of the Zygor Guides (5.0.11221 -> updated this morning EST).

I have not attempted to reproduce the error on another machine, since I don't' have one.
I have however formatted my machine, and reinstalled a brand new version of WoW with a brand new version of Zygor Guides and I still get the same error.

I run a few addons (most of the popular ones), and I can list them if you like

This is a Blizzard bug that affects several addons. Someone has created a 'fix' addon to stop the LUA errors from happening when a quest item is clicked. You can get that here: http://www.curse.com/addons/wow/questitembuttonfix
