Well it didn't work when I tried too. But now it shows again for some reason.
But still it is bugged, the sidebar still shows on the bottom of the page as on the picture that I posted.
The reason is simple, you've made changes to css, but the changes are not correct.
Solution - Remove all changes you have made and restore the original css and everything is OK.
To avoid such a problems in future, do only such changes, what You know how they must be done.
