I recently asked a question here on the main site. The $\LaTeX$ in one of the answers doesn't render. It isn't a problem with the syntax, it renders on the answerers browser(Firefox). Attached screenshot belowenter image description here

The poster attached a screenshot of his rendering so I could read, so the screenshot of the screenshot is also present, which can be read.

    $\begingroup$ The question renders fine for me on Chrome 33.0.1750.146 m (under Windows). $\endgroup$ – Martin Sleziak Mar 13 '14 at 12:26
  • $\begingroup$ I've deleted here the % at the end of \sum_{k=0}^{n}\binom{k}{1}+2\binom{k}{2} $$\begin{eqnarray*} S &:&=\sum_{k=1}^{n}k^{2}=\sum_{k=0}^{n}\binom{k}{1}+2\binom{k}{2} =\sum_{i=1}^{n}\binom{k}{1}+2\sum_{k=1}^{n}\binom{k}{2} \\ &=&\binom{n+1}{2}+2\binom{n+1}{3} \\ &=&\frac{n\left( n+1\right) \left( 2n+1\right) }{6}. \end{eqnarray*}$$ With that %it didn't render here in this comment box. $\endgroup$ – Américo Tavares Mar 13 '14 at 12:27

    $\begingroup$ @AméricoTavares yes the modified version renders now. $\endgroup$ – Guy Mar 13 '14 at 12:28
  • $\begingroup$ @MartinSleziak that could be it. My chrome is ancient. 25. $\endgroup$ – Guy Mar 13 '14 at 12:28
  • $\begingroup$ @Sabyasachi I will delete the % in my answer at the main site. Done. $\endgroup$ – Américo Tavares Mar 13 '14 at 12:31
  • $\begingroup$ @AméricoTavares okay. thanks. rendering perfectly now. :) You can remove the screenshot if you want to. $\endgroup$ – Guy Mar 13 '14 at 12:34
  • $\begingroup$ @Sabyasachi It's a strange behaviour, because that % was at the end of a line. $\endgroup$ – Américo Tavares Mar 13 '14 at 12:36

    $\begingroup$ Some browsers remove line breaks, and that appears to be what happened in Chrome, so the comment became the entire rest of the equation, and it didn't render. Had the line break been retained, you would have had a multi-line error box. $\endgroup$ – Davide Cervone Mar 13 '14 at 23:38
