Sometime earlier today, I started getting this alignment problem on all User Profile pages on EE.SE (both main and meta sites). See an example below:
I added the red rectangles to show the empty spaces that appeared in place of the usual content.
Is it just me? I tried it on Chrome and IE and both showed the same problem.
Here's another screenshot showing more page contents. It looks like the rest of the page is shown on the left column. Before the glitch, the content used to be distributed among two columns.
