Crashes when i open Character Panel

As the title states. My wow crashes everytime i try to open the character panel, or reputation panel. it only started to happen once i reached level 800.

Please if anyone has a solution do share it, it's pretty annoying when it keeps crashing.

For C bug just type below :

/console PlayerStatrightdropdown Melee
/console PlayerStatleftdropdown Melee
/console reloadui

or in game click hearthstone >> fix c error

oh thanks, lol didn't think of the fix c error thingy..

thanks much!
