I put them all in the addons folder within the Interface folder and I did so correctly (I did look at the faq and made sure they were placed there correctly)
When I log in, I see the Addons button on the bottom left and I enabled all the Deadly Boss Mods there as well and checked "load out of date AddOns". Additionally, there aren't any missing dependencies either.
However, my main problem arises when I actually enter world and try writing /dbm or /dbm help - all I see is type '/help' for a listing of a few commands. I've tried deleting the respective addons and re-installing them, but I keep getting the same error. I don't know how to resolve this problem.
Any help that you can give me on how to fix this is greatly appreciated.
