Is your blogsome’s sidebar shifted ?
To check whether your blogsome’s sidebar shifted, you must use IE not firefox. This is happen when you insert a picture more than their css allowed, for my case i should not insert more than 200 pixel picture. When i did, in the IE my blog’s sidebar will look awkward (it will showed in the bottom instead of in the right top).
To overcome with this problem you have 2 choices : first is to insert smaller picture below 200 pixel, second you can alter the css setting to more than 200 pixel). To change the css style change setting on menu Manage-Files-Site Style Sheet, you will see this:
Increase the value to more than 200px (250px suggested).
As with my case i reduce the size of the picture below 200 px, so i don’t need to change the css style
