Hello everyone, i think i’ve gor really serious problem.
I started to modify the free wordpress theme (aligned)
posted some random posts and then made some structure and visual changes.

this is a normal single post (i posted before changes): http://imageshack.us/a/img689/1762/cumd.jpg

and this is a post i posted after the design and structure changes: http://img199.imageshack.us/img199/4707/kx7c.jpg
