my addons menu is not appearing

my addons menu is not appearing neither charecter selection not ingame

If it does not appear, your addons are not installed correctly. There should be .toc file directly in each addons folder. Make sure there are no extra folders in between.

http://prntscr.com/kbly37 see that img even blizzard addons are not appearing

The button does not appear if you have only Blizzard addons in AddOns folder.
