Hello everyone.
I just started to work on my forum and I noticed something wierd, or at least I don't like how it looks! it's ugly!
When I post something it looks like in the Untitled.jpg attachment, and the second attachment is how I want to display it (example).

Can you please help me?

Theme code is broken. Provide us link of your from so we can take a look in code. And also you can change theme which works properly.
