Latex equation stops working

Hi, Jack. Got some new problem.

From yesterday (or maybe earlier), the display of any newly edited latex math expression is not working properly. It echos "Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)):" + any latex source code. See the bottom of this page or the equation below as an example. Please take a look, thanks!

<math>\mathcal{F}=ab\sqrt{c}d^2</math>

Problem with LaTeX equation display

Hi, Jack. I kinda figured out that there is a quite hidden issue with LaTeX equation which is quite annoying.

The problem involves the typeset mathcal (and the like, as far as I noticed). When one uses \mathbf{ABC} it seems to work well. However, when one uses \mathcal{ABC}, it does display correctly for the moment, and then the page goes through some compiling process (which takes a while) and eventually display the normal typeset.

<math>\mathbf{ABC}</math>

<math>\mathcal{ABC}</math>

(The above was well interpreted for few seconds then turned into another form -- less elegant)

In fact, it takes the same amount of time for the wiki to interpret (sometimes, not really correctly) other LaTeX markup such as cal

<math>\cal{ABC}</math>

(The above was in red for like 5-20 seconds and then turned into normal)

Thanks a lot! Gamebm (talk) 17:40, 22 October 2014 (UTC)

Apologies for the delayed reply, I somehow managed to miss this message...sorry!
What browser/OS/their respective versions are you using? I think that the issue you're describing is a bug, but I don't know what's causing it or how to fix it; you should report this on our Bugzilla or maybe even on the upstream bug tracker, Wikimedia's Bugzilla. MediaWiki's math support is a rather obscure and scary component well understood only by select few developers. --Jack PhoenixShoutWiki Staff (Contact) 21:10, 4 November 2014 (UTC)
Hi Jack, thanks for the reply. I just did the test, it happens both on Chrome 38.0.2125.111 m and Forefox 24.0, the operation system is windows 7, it happens on both of my two desktop computers. One need to wait a while to see the problem, in my case, it takes 10-20 seconds. The fonts were ok at first then changed their form. Gamebm (talk) 00:26, 5 November 2014 (UTC)
I reported it to Bugzilla as you suggested: Bug 289 Gamebm (talk) 00:46, 5 November 2014 (UTC)
