Hi,

so I found the reason. Both Org versions behave the same, sorry for the
confusion. The original equation that does not get exported correctly contained
angles:

\begin{equation}
  <k_{eff}> = \frac{\sum_i w_i k_{eff}(i)}{\sum_i w_i}.
\end{equation}

This equation is correctly rendered when using a .tex file and native LaTeX.
If the angles are removed, the Org Mode HTML export works:

\begin{equation}
  k_{eff} = \frac{\sum_i w_i k_{eff}(i)}{\sum_i w_i}.
\end{equation}

Does anybody know why? Is this expected behavior? Can this be changed?
