I have no idea,
is this a bug or there is something wrong with the way I post a news.
I try to insert this code somewhere between my post:
<div class="blablabla"><hr /></div>
And, when I saw the result with browser, my Tidy plugin give me a warning alert. There is something wrong with my tag, unneeded <p> tag without closing </p> tag.
<div class="blablabla"><hr /><p></div>
And then, I try to fix my post which contain unneeded <p> tag. But, I found more weird result with my post that I'm going to edit (i'm using code tab - not visual).
the code become: <p class="blablabla"><hr /></p>
now, that is not funny :D
I've done enough test about this problem,
and I'm pretty sure that there is something wrong.
Sometimes it is ok, sometimes it isn't.
Now, I don't want to edit my post again - it show me the correct code now.
