LaTeX Why are MathJax images not displaying on my webpage?

[micromass]

Oh no, that site has a picture from when I met Stan Lee:

Problem solved!
I had to turn on my Windows Cleartype.. Maybe helpful information for other people around here, because the rendering is now done by the browser, so quality can variate.

Attached is a comparison with cleartype on/off, it really makes a difference:

Looks like the problem was there with normal text as well, but the thinner strokes in the math characters made it more pronounced.

FYI to IE users! Just received this response from a developer:

There are a number of security settings that affect the operation of
MathJax. I did some testing in IE7 (for a different report of the
same issue), and found that there are at least four important settings
that can cause MathJax to not process the page. They are accessible
in the Internet Options menu item (in the Tools Menu) under the
Security tab. If the security setting is set to "High" it sets
disables all four. You can use the Custom Level button to change the
following:

First, you need to make sure "Active Scripting" under the Scripting
section is enabled (near the bottom of the list). This allows
Javascript to run (or not). If Javascript is disabled, MathJax will
not be loaded or run, so this one is critical. Since you are seeing a
javascript error message, I assume this one is enabled for your
limited account.

Second, you need to make sure "Run ActiveX controls and Plugins" is
enabled (or prompted) in the "ActiveX Controls and Plugins" section
(second to last option). This is the setting that is causing the
error that you are reporting. The line you indicate is one where
MathJax is trying to set up MathPlayer (which is an ActiveX control),
and if this setting is disabled, IE throws an error.

Third, you need to make sure "Script ActiveX controls marked safe for
scripting" is enabled (or prompted) again in the "ActiveX Controls and
Plugins" section (last option). It requires a restart of IE if you
change this setting. This is needed in order to allow MathJax to
create an XML parser, which is used in the MathML input jax.

Fourth, you need to make sure "Font Download" is enabled (or prompted)
in the "Downloads" section. This is required for MathJax to use the
web-based fonts. Without this, IE will time out waiting for the first
font, and then fail over to image fonts, so it is not strictly
required, but makes for a better experience.

Currently, whenever the NativeMML output jax is configured, it tries
to register MathPlayer in IE, and whenever the MathML input jax main
code is loaded, it instantiates the XML parser. Since you are using
the TeX-AMS-MML_HTMLorMML configuration, you get the NativeMML output
jax as part of that regardless of the renderer for the page. That is
why you are seeing this error. You can avoid the error for now by
switching to the TeX-AMS_HTML configuration file instead, but this
means you users would have to switch to the MathML renderer manually
in order to use their native MathML support (if any).
I will look into changing the timing of the setup for MathPlayer so
that it will be attempted only when the renderer is explicitly set to
MathML, which should avoid the problem in most cases. It is probably
possible to trap the errors for the second and third settings as
well. But as long as those settings are in place, MathJax will not be
able to use MathPlayer to render mathematics, and it will not be able
to parse MathML input, so some MathJax functionality will be
unavailable.

Can't... stop... laughing... help!

That's good to hear I almost thought I was the only one laughing when no one showed any appreciation for more than 4 hours.

 

[Greg Bernhardt]

FYI the devs have told me that the "Loading ..." messages problem will be fixed in the next release

I have sent two emails two whomsoever, immediately before and after pressing the run button on the linked page.

I could see the quadratic formula on the mathjax page, no problem.

Since there has been no improvement to my viewing of formulae I wondered if there had been any progress on my discovery that the problem only arises if the user has limited privileges (as mine and nearly all corporate ones do)?

go well

The devs are aware of this problem and say an update will be released in the next week that should resolve it.

Looking forward to it.

All the 4 items in your post #273 have been enabled for a while, to no avail.

 

[Studiot]

Sorry to be a pest but all I ended up with on emailing (clicking the button on the webpage) the mathjax test was two emails in my outlook express box, without recipient.

Now my OE does not work.

I can still transfer these to webmail, but do not know the recipient, please?

 

[Studiot]

Edit

I think OE is working it just gives an error message because there is not recipient.

 

[Greg Bernhardt]

ah yes, one sec

ok you can submit now

 

[Studiot]

Yes boss done.

 

[Borek]

Sometimes there is not much to report...

And when I have problems, it always looks identical - 15 seconds waiting for downloads, I guess that means timeout.

 

[Borek]

No, looks like it can get different - now LaTeX was processed, but Opera still waits for servers.

I have three reasons to use Opera - first, I have zillions of usernames and passwords stored in Opera configuration files. Second, I paid to register Opera in 2004, when it was ad-sponsored. Third - nobody uses Opera, so it is rarely (if ever) targeted by hackers. Unfortunately lately using Opera to access PF is becoming a PITA (it works OK on other sites I visit, but I spend most of the time at PF), so I may have to think it over again

 

[Greg Bernhardt]

Are the results in the image relatively constant?

 

[Borek]

Usual pattern looks more like this.

(And when I want to show this 15 sec timeout everything works perfectly, why should it not?)

I gtg for now. Keep posting interesting results and I will compile them and send them to the devs later today. thanks!

 

[Borek]

OK, that's the timeout. Note that on the first image it shows timeline, but Opera still waits for mathjax server.

The devs are aware of this problem and say an update will be released in the next week that should resolve it.

You can fix it now by using TeX-AMS_HTML instead of TeX-AMS-MML_HTMLorMML.

The main reason why that idea bothers me a little is that $$math$$ has the same effect as
math
in a LaTeX document, i.e. it has the same effect as tex tags here.

Uhh...I don't know why MathJax turns that into an image. Click quote to see what I typed.

You could also change this behavior Fredrik saw by setting processEnvironments to false in the tex2jax parameters. On the other hand, perhaps you'd prefer MathJax, like TeX, to process anything between \begin and \end as math without needing to type in delimiters.

Can we make it so clicking the [PLAIN]https://www.physicsforums.com/products/latexreference/images/Icon3.gif icon inserts itex tags instead of tex? I'm finding a lot of new members using tex for LaTeX code that is supposed to be inline with their text, and it is breaking up expressions into multiple lines.

Also, I have updated the LaTeX stickied thread in Forum Feedback.

I never use that button, but I would guess that it's both possible and preferable to replace it with two buttons, one for itex and one for tex.

for the meantime I switched it to itex

Thanks Greg!

I don't know if that is the root of the problem, but we'll see if we stop getting posts from new members like this:

Homework Statement

Three sinusoidal waves of the same frequency travel along a string in the positive direction of an x axis. Their amplitudes are y1, y1/3.0, and y1/4.0, and their phase constants are 0, \pi/4.0, and \pi, respectively. What are (a) the ratio of the amplitude to y1 and (b) the phase constant of the resultant wave?

Even if you're aware of the issue, it's easy to miss that one of the phase constants is \pi/4.0

 

[Greg Bernhardt]

1.1a is due out tomorrow afternoon!

 

[chroot]

Greg, is there anything I can do to help?

Thanks Warren! I think we're in pretty good shape.

I believe 1.1a is now out. Those who were having problems please report any differences. Remember to clear your browser cache as the JS is cached for two weeks.

I tried visiting the forums using a limited account in XP, and the access-denied problem no longer occurs.

Any decision on new delimiters?

 

[Studiot]

Greetings from the land of XP limited privilege users:

Whatever you did 10 minutes prior to the timestamp of this post suddenly worked properly.

The yellow error triangle was no longer evident and I thought tex worked again.

However now the issue has returned.
