Discussion Overview

The discussion revolves around issues related to displaying LaTeX formulae on a forum, specifically the appearance of a "Math Processing Error" message instead of the expected mathematical expressions. Participants explore potential causes and solutions, focusing on browser settings, JavaScript functionality, and cache management.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant reports seeing a "Math Processing Error" instead of LaTeX formulae, suggesting a possible setting alteration on their browser.
  • Another participant inquires whether the issue occurs with specific posts or all posts and suggests checking for JavaScript blocking or strict firewall settings.
  • A different participant mentions experiencing similar issues with raw LaTeX being displayed and notes a potential change related to the forum.
  • One participant shares that switching to a different browser (Firefox) resolves the issue, while Chrome continues to display errors despite enabling JavaScript and adjusting other settings.
  • Another participant clarifies that LaTeX rendering relies solely on JavaScript and inquires if the cache has been cleared.
  • A participant confirms that clearing the cache in Chrome resolved the issue, allowing LaTeX formulae to display correctly.

Areas of Agreement / Disagreement

Participants generally agree that the issue is related to browser settings and JavaScript functionality, but there is no consensus on the exact cause or solution, as experiences vary among users.

Contextual Notes

Some participants mention potential changes in browser settings or forum configurations that may have contributed to the issue, but these remain unresolved. The discussion includes references to specific browser functionalities and settings that may impact LaTeX rendering.

Anyone recognise this problem?
When looking at posts with (presumably) Latex formulae, I get [Math Processing Error] instead of the formula.
It looks like everyone else can read them ok and even stranger, I sometimes see the formula for a brief moment before it is replaced by the message. What I'm seeing is the rendered formula, not the raw Latex.
I suppose it must be some setting I've inadvertently altered, but what is it ?
I'm using Chrome and Windows 10 Pro on a 32bit HP.

Specific posts or any post with latex? Are you blocking any javascript or have strict firewall settings?
 
Thanks. Seems to be all posts. I'll check the Javascript - sounds a distinct possiblity.
 
At least we are not alone. I too am seeing the raw latex, lots of ##, etc. Been happening for ? months. JAVA is turned ON, many sites won't work at all when OFF. There seems to have been a change somewhere related to PF. I recently had a problem with an "Untrusted Site" that hosted some required file for showing icons, now this. (Old browser here.)
 
For now I've done what I should have thought of first, use a different browser. So I'm seeing things ok in Firefox at the moment.

In Chrome I checked Javascript was enabled, but Flash was not. Popups were also blocked. Enabling these didn't help immediately, nor after restarting Chrome, so I'll reboot the whole thing and see if it's made any difference.
(Sleep intervened.)
Even after a full reboot with everything unblocked, Chrome is still giving the error. FFox is ok.

The LaTeX formulas have nothing to do with Flash or popups, they are purely based on JavaScript.
Did you clear the cache?

Thanks for that. When Javascript was already enabled, I turned the Flash & popups back on as they were the only things turned off!

Clear the cache? Well, I'll have to look at what that might be.
And sure enough Chrome has a cache for files and images. When cleared, formulae fine.

Thank you mfb.

Now, if I can find out how to do it, I'll thank you and mark it solved.
