hey Little Pockets :)
whats your level of tech expertise? Una is not simple, but also not complicated. But- all things considered- it is not beginner. The cloud offering may be, however it's at a lack for customization I would imagine.
I first ran una, and like you, tweaked every knob, and so on- and had a lot of fun, felt like i was really getting somewhere, had a site working and creaaking along for a aaaa maybe two weeks? or so before i blew it up tweaking more buttons and knobs..
then i did something unexpected as the "why" kid. who literally grew up disassembling house hold electronics, toasters, microwaves, etc..
i just installed una. and left it alone. and used it.
and slowly, but surely- i noticed something that made me both really *&*&** mad at myself, and really brought a lot of laughter too.
all the stuff you are trying to do all up in here??  its all built in already just seriously stop you will drive yourself nuts or at least waste a lot of time,  just erase everything install it, and just try it all out for a month or so before you really turn any dials.  have fun :)

also, focus on initially getting most of the things on the server audit satisfied, however note there are some exceptions, like you can be totally running apache 2.x and it come up as 'undefined'  you are indeed running it, otherwise your site wouldnt show up.
speaking of, one last thing. wheres your site? ill join and kick the tires around as a new member. no judgement, just to get an idea of where you are at in your project/build... if you'd like. also, you may check out my una site- it's free- its www.mytribes.net
