# Bug Mathjax problem

#### PAllen

Yesterday, latex was fine. Today, all posts with latex get "Math Error". No changes on my machine. Anyone else seeing this?

Works OK for me.

#### PAllen

Now it works fine for me too. Same machine, browser, etc. Didn't work then, works now. All is fine for now.

I'll post about mathjax later tonight

My Latex has also stopped working. Wherever I once saw perfectly fine latex text, I now see "Math Processing Error" in red. I haven't installed anything new.

Earlier today I had a few of those errors, then all was fine.

Now I get that error for ALL LaTeX code.

$\displaystyle \text{Like this .}$

I'm not getting any explicit error message, but LaTeX is not rendering correctly for me. It looks like what Sammy showed, above.

I'm running IE 9. I tried logging out and logging back in, and was not able to open the PF site for about an hour, possibly a different problem.

EDIT: I just tried closing IE, and then restarting it, but that didn't change things.

No success yet, after clearing my browser's cache.

Greg,
It seems to work fine on IE8, which I'm running at home. I'm having the problems on two machines at work, where I'm running IE9. I think they might be having problems loading one or more of the js files.

If the problem is still there tomorrow I'll attach a screen shot, or if the problem goes away, I'll say that. Either way I'll get back to you tomorrow.

. . . got trouble in River-city looks to me. I mean don't you hate that, install an update then bam! stuff stops workin'. At least we're not FDA-regulated. Discrepancy meetings, heads on the block, revalidations, all that stuff. Yeah, mine's not workin' neither but I try not to be a pain or nothin'.

Still not working. Here's a shot of what I'm seeing.

The pi and pi/2 parts are inside [ itex ] and [ /itex ] tags.

#### Greg Bernhardt
