Chances are updating single addons that a tweaked to fit into a UI will break it. Example is Real UI . Wonderfully minimalistic . Upon firing up the MMOUI Minion updater, I realised that half the addons were outdated ( but still work ) . I updated the ones that I felt were necessary and that broke the UI
Heres a few things I can help you with
1 ) Name me the addons that you feel need to be updated and I could try to see if it would go smoothly or it would not work at all
2 ) I could suggest CleanUI , it looks almost EXACTLY the same as Alza ( no really it does ) . The author loved ALZA and when it stopped being updated, he decided to make a new one
3 ) Look through the Screenshot of your UI thread, I can guarantee people in there would be able to help your recreate the look and feel of ALZA with no problems
