mathjax failed to load on Chrome

[Phạm Văn Thuận]

Hi,

Mathjax has recently failed to load math pages when viewing by Chrome. This did not happen until recently. IT is OK with Firefox and IE. Could you help?

Hi,

The only error I can see is due to a typo in your configuration -- it has to be "AMSmath.js". 

Otherwise the page runs fine in Chrome 31beta, Chrome 28.

Best,

Peter.

The current problem occurs with my Chrome on Macbook only. For other laptops, Chrome still works well with mathjax page.

Hi,

We need more information than that -- see the User Group guidelines for advice. For example: Which version of Chrome and Mac OS are you using? What exactly are you experiencing? Does the JavaScript console report any errors?

Please fix your configuration first -- the MathJax.js call has to come AFTER the configuration, see http://docs.mathjax.org/en/latest/configuration.html#using-in-line-configuration-options, and the typo I mentioned is still there.

Peter.

Hi Peter:

We have Chrome Version 30.0.1599.101, and OS X is 10.8.4 The problem is that maths formulas just generated between 40% and 60% of the pages. Then the page is NOT responding moments then on and on. We use Mathjax for some subpages on our website hexagon.edu.vn only for the one that require math formulas.

Attached is the print screen of the problem. 

It is AMSmath.js extension already. 

I guess the error has something to do with Mac OS X because we try other pages in Vietnam that use Mathjax with thís Chrome and Mac, then the same problem occur. For Safari and Firefox, IE, No problem at all.

Peter has already pointed out the problem.  The capitalization of the AMSmath extension in your configuration is incorrect; it should be "AMSmath.js" not "AmsMath.js".  File names are case sensitive, and need to be capitalized properly in order to load.  

I am able to view the page with Chrome 30.0.1599.101 on Mac OS X 10.7.5.  Though I do see the message you indicate, the page does render (since it doesn't seem to use any of the AMSmath features).

[Phạm Văn Thuận]

Yes, it works well now. Thank you.

Hi Mathjax team:

Today the same problem is coming back after months of smooth running: It can not work properly with Chrome on my web

http://www.hexagon.edu.vn/dien-dan/giai-bai-vmo-2014:-olympiad-toan-quoc-gia-2014-nd168.html

Can you help me?

Hi,

I'm afraid everything is working as expected on my end. 

It might be a DNS resolution or endpoint issue. Can you ping cdn.mathjax.org and tell us which akamai server responds (if any)? Alternatively, can you ping https://c328740.ssl.cf1.rackcdn.com?

Peter.

[Davide P. Cervone]

It works for me as well.  Can you say more about what isn't working for you?  do you see "Math Processing Errors", or does noting happen?  Are there any error messages in the browser console?  Does reloading the page help at all?

Did you update your version of Chrome recently?  Did you update the system?  Only other local changes to your system?

Try clearing the cache and restarting the browser.

Davide

The pages that contain math formulas in my website today all experience the same problem: the content does not load enough. It just reports "typsetting math" as you can see in the screen shot attached. No Math Processing Errors at all. Reloading the page or other pages that have math jax in my web does not work.

Three months ago, the same problem occur then you told me to correct the capitalization AMSmath.js, then everything was OK.

I have ping the cdn.mathjax.org as you suggest. It is fine now. I am still wondering why this happens on Chrome only, and other website users of mine may not know how to solve this and they would not be able to see the content.

Hi,

If you run into such trouble again, please send us the MathJax log. You can produce this on the JavaScript console in the Chrome Developer Tools by entering  

MathJax.Message.Log();

This may help track things down.

It's hard to diagnose such a localized problem. If things improved after clearing the cache, then you probably had a corrupted file in the browser cache. That can happen and is most often caused by slow or unstable connections (such as on mobile). Clearing the browser cache forces your machine to download all files again, hopefully without corruption (assuming the corrupted file wasn't cached on a proxy server). 

Since MathJax downloads multiple files, it's not easy to determine which component/file is the problem. Since MathJax is highly modular, you may also see problems only on those pages where MathJax needs the features provided by the corrupted files, while other pages will render just fine which gives the impression a single page has a problem rather than the cached MathJax files.

Hi Peter:

Today we got the same problem with Mathjax. I have produced  the MathJax log in the Developer Tools of Chrome  in the file attached.  

This problem occurs for Chrome only. Just fine for Firefox?

We just transferred new host a few days ago.  But why we have trouble with Chrome only.

Hi,

The screenshot indicates that MathJax has not loaded at all (but there is no error indicating why MathJax.js was not loaded). It's hard to say without a live sample why that might happen. The link on your original posting still works fine for me so I cannot reproduce any issues.

Looking at the source of your page, the inline configuration block is using a very outdated format which might lead to processing errors. Please see the page in the documentation for how to fix this. This might help (although it seems unlikely for me).

Regards,

Peter.

Hey,

I am encountering the same problem. Mathjax is not loading in chrome. If I try to access cdn.mathjax.org i get an error 

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<Error>

<Code>AccessDenied</Code>

<Message>Access denied.</Message>

</Error>

I use iversity.org which is where mathjax is not loading. Specifically this link 

https://iversity.org/my/courses/vehicle-dynamics-ii-cornering/lesson_units/27221

Im using Version 37.0.2062.103 m 

Please help me rectify the issue.

[Peter Krautzberger]

Hi,

cdn.mathjax.orgmaps to our Google Cloud Storage. The response for the domain itself is not important. Rather, it's important to reach urls like http://cdn.mathjax.org/mathjax/latest/MathJax.js. 

If you have trouble with a specific website, please inform the admins of that website of issues. In this case, Iversity is using the recently retired rackcdn address; you could point them to http://www.mathjax.org/changes-to-the-mathjax-cdn/ for reference.

Regards,
Peter.

The same thing happened to me today, on chrome (Windows XP). The mathematical formula is in the form of tex code. If I click with the right mouse button, the mathjax menu does not appear..

CloudFlare's https encryption no longer works with Chrome on Windows XP. Also, Chrome no longer supports Windows XP.

Peter.
