I have used old login data you provided to check things. Sorry for not asking, just wanted to get things done.
About it, Blog main page is only(portfolio main page, might suffer also) place where shortcode slider wont work, as wordpress just don't even read that page, only use it as place for posts :-)
Slider that was trying to show its self was from your first(by date) post, but it was broken anyway.
You can set slider in some post and if you put it before more tag it will be used on blog main page(if this post is listed). But best is to use more tag on all posts, and adding sliders no bottom of post/page.
