Addons not working on 3.3.5 Lordaeron

So to sum up this thread so I don't waste your time, I've downloaded addons from either curseforge or wowace(the 3.3.5 ones) then I put them in the Interface folder then I deleted the cache and wtf folder. Before I log in I make sure to check all my addons so they actually load and set the load out of date addons. But when I log in some addons don't work at all(they haven't loaded) or if they load they don't work correctly at all and don't even respond with the appropriate commands. I'm using the same WoW client that I've always used when playing on Warmane and have absolutely no idea what I'm doing wrong. Any help is really appreciated.
