Forum Some posts align to left of page error
 

When I make a post on my forum, the text is tiled to the left of the page which is very annoying.

I use Google Chrome, but I've tried it on Firefox and I get the same thing.

Here are some screenshots to show what I mean:

This post is tiled to the left of the page, like this: Link

But the second post is normal, while the post below that is also tiled to the left: Link

Right after I make a post I sometimes do see the text normally, and also when I use the edit function, but when I return back to the thread later I get the same tiled to the left error.

Here's another example from a recent post I made:

Right after I edited it: Link

When I go back to the thread: Link

Does anyone know what might be causing this, and what might fix it? Any help would be greatly appreciated.
