I have a very old character from Vanilla that I have not played in years. I just decided to hop onto it again with Warbands and I encountered an odd bug. For this character only, I cannot enable Bar 6 or Bar 7 and the "enable" checkbox is missing. I have tried deleting my WTF files for this char, no luck. I have tried different profiles, no luck. I can use the exact same profile that this char is using on any other character and the issue is not present, including if I make a new character and use that same profile. Only this specific character replicates the issue. If I disable BT, I can enable Blizzard Default Action Bars 6 and 7 without issue on this character. I tried doing a "/console cvar_default" command, but that also had no affect on this character-specific bug.

Any idea what is causing this? I know it's a very obscure case, so I am guessing it's some kind of legacy setting, but I have tried a lot and haven't had any luck.

I enabled console script errors and BT flags this error on the affected character:

I fixed it!

The solution was to disable BT, reload, then (on default action bars) remove all spells from the action bars. After that, I reloaded and re-enabled BT and bars 6 and 7 worked again!

Some kind of weird legacy bind? Not sure, but glad it works :D 

More info: it specifically appears to be the dropping of the Rogue poisons container into an action bar that causes this! As in the clickable/expandable group spell for all poison from the spell book. Individual poisons don't seem to do anything, but the group poison button breaks it.
