math processing error (forum)

[sarepairman2]

i noticed when i reloaded the page a "math processing error" showed up in reed text. did anyone notice this before? curious. almost a subliminal error message.

i'd be wary of it being a exploit vector to hijack the forum

It think it is a LaTeX plugin doing this. Every time I reload a page there is some garbage appears and goes away quickly.

I've noticed it a time or two, too.

Yep, it is a LaTeX thing:

I believe this is due to the LaTeX thing, but I might be wrong - is anyone else seeing the

Code: [Select]

\( \renewcommand{\renewcommand}{} \)
at the top left of the page for a moment when it loads?
It happens whenever I open/refresh a page and disappears after a second or so.
Just wondering. 

Tested working on Chrome OS 49 beta, Firefox 44 Android (on full site mode), Chrome 47 64-bit Windows
Doesn't work on IE9 (eek)

I use the NoScript plugin, which disables JavaScript from all domains except those which I have authorised. It speeds some sites up significantly, as well as letting me see who is trying to track me

I now see that "renewcommand" at the top of every page, and also that "mathjax.org" is waiting to be loaded. When I enable mathjax.org's JavaScript, the "renewcommand" disappears.

Conclusion: yes, it is a Latex/mathjax/JavaScript thing.
