#1 - When posting about a specific addon, you should always include a link to the addon's download page. This site hosts thousands of addons, and people are more likely to help you if they don't have to go hunting around on search pages to figure out what you are asking for help with.

m_ActionBars has not been updated in a year, none of the author's
other addons have been updated since March, and
the author him/herself hasn't logged onto the site since September. This addon is clearly not updated for WoD. You should probably look into alternatives.
