Thread:Project:Support desk/Javascript not working in custom skin

I just founded a wiki and have made a new skin that is partially based on Vector, and I noticed that a lot of javascript functions including keyboard shorcuts(e.g. alt+r for RC), editbar(buttons on the top of text editor), and MediaWiki:Common.js were not working at all. I am barely able to figure out what is going wrong, since it is my first attempt to build a wiki outside of wiki farm. I am using MW 1.19.2 and  is set to true. Any suggestions would be really appreciated.
