Not sure what that latex is doing in there. The following works as normal
HTML for me:

--8<---------------cut here---------------start------------->8---
* foo
Here's a formula


$\int_0^\infty e^{-x^2} dx = {{\sqrt{\pi}}\over{2}}$

$latex z * k^\theta$
--8<---------------cut here---------------end--------------->8---

A few things: the default way to export fragments is through MathJax:
there may be some sort of a setup problem that prevents MathJax from
working with the blogging stuff.  You might want to fall back to
png images and see if that works better for you (you'll need dvipng),
although that's usually seen as a step back.

The preferred way to enter math in latex (and in org) is with \(...\)
for inline formulas and \[...\] for displayed ones. $...$ will work with
certain restrictions noted in the org docs (see below) for the inline
case, $$...$$ does *not* work for the displayed case (it's not even legal
LaTeX).

C-h v org-export-with-LaTeX-fragments RET has the details.

(info "(org) LaTeX fragments") has more on $...$, mathJax etc.
