help….

I have been playing with new blog templates for a while and now have this problem:
My blog removes the formatting of my posts. See the posts below.

Please let me know what needs to be done…
Even if I revert to my old template I am seeing this problem.

Help…

PS: Even this post will appear in a single line though it has 8 lines.
I am expecting imse to help me, as he is the guy who asked me to change the template 🙂
