Description:
In contrast to local execution, the MathML elements are filtered out on betalabs.
See for example

 F n = ∑ k = 0 ⌊ n − 1 2 ⌋ ( n − k − 1 k ) . {\displaystyle F_{n}=\sum_{k=0}^{\lfloor\frac{n-1}{2}\rfloor} \tbinom {n-k-1} k.}
rather than
Fn=∑k=0⌊n−12⌋(n−k−1k).<script type="math/mml" id="MathJax-Element-5"><math xmlns="http://www.w3.org/1998/Math/MathML">

the Math extension returns the result as return array( $renderedMath, "markerType" => 'nowiki' );

which should prevent the output from further processing.

To reproduce this error you have to log in to
http://deployment.wikimedia.beta.wmflabs.org/wiki/
and to change your rendering mode to MathML in your user prefrence section.

PS: Sorry for including the SVG. That was not intended.
