latex path not specified errors
-
Why are you posting into this wordpress.com thread then? We provide support only for blogs hosted here and no others. Go to the relevant thread for your own software and post there only please.

-
Creating multiple threads and referring to wordpress.ORG sites simply creates confusion. Only some folks are on wordpress.ORG installs on paid hosting. The others like chadmspooner are in fact hosted by wordpress.COM.
-
As far as I can tell the issue has now been fixed on all the blogs that I knew of that had problems.
-
I take it back; on the blogs I checked (including my own, and all hosted by wordpress.com) all the images that weren’t rendering before are now rendered properly, but when I just now tried to put in some new LaTeX snippets to render, I still get the “latex path not specified” error. Not sure exactly what happened.
-
Further update: now it seems the problem is machine dependent: I am seeing rendering errors (both for snippets that were previously problematic, as well as fresh test snippets) on my phone and laptop (using either Chrome or IE), but not on my desktop. This makes no sense to me!
-
For instance, on some of my machines, the first post in tcsmath.org is full of rendering errors, but on another of my machines, everything renders fine, regardless of which browser is used.
-
@timethief, objection on the part of your understanding of the process. I created only one thread here on wordpress.com, responded to another, and pointed to only one thread on wordpress.org, per your request.

Nothing has changed for me since my previous post on this thread.
(To be clear, my blog is on wordpress.com.)When I insert any latex code in a draft post, and preview it, I just see “latex path not specified” in the preview.
When I insert new latex fragments into a previously published post that itself contains many equations, all the previously written equations and latex fragments (inline, for example) look great, but the new ones do not appear, only “latex path not specified” appears where they should be.
To test whether this was a problem only with “preview”ing a post, I modified a previously published post and went off to the internet to look at it. The newly inserted latex fragment does not appear, just “latex path not specified.” All other latex code renders correctly, as it did in the past.
I’d like to help wordpress more, but I’m not sure how to at this point.
timethief, can you verify that wordpress is looking into this?Thanks.

I found that on my URL (www.malcolmgin.com/geekblog), rendering seems to be partly to do with the Chrome browser I use and partly to do with page zoom. With the view on zoom level 90% or 100% , the page renders as expected. At a zoom level lower than 90% or higher than 100%, I get the “latex path not specified” error messages instead.
Testing with mirdonamy’s newvillagegirlsacademy.org site, this didn’t fix the issue I was seeing on that site. But I also noticed that my latex rendering URL is http://s0.wp.com/latex.php and mirdonamy’s is using l.wordpress.com/latex.php and perhaps the two latex.php scripts are somehow configured differently?
This, by the way, answers @timethief’s question as to why this topic is here on wordpress.com. The latex rendering utility script is running on wordpress.com URLs, not wordpress.org URLs.
-
The browser page zoom setting has no effect on this bug for me.
As far as I can tell, latex functionality has been broken simultaneously with the release of the new editor. I chose wordpress for its good handling of latex in the first place, so this is disappointing.
Hoping to hear from WordPress.
-
Same issue in my blog. Looks like parenthesis break the rendering somehow. For example, $latex x$ works but not $latex (x)$
-
I almost get the same behaviour with malcolm’s page http://www.malcolmgin.com/geekblog, except that the images render at all zooms up to 100% and fails above 100%. The site newvillagegirlsacademy.org fails even on the one machine of mine which is inexplicably rendering everything else correctly, so it does seem that the issue is coming from the latex.php configuration.
In a recent post of mine https://terrytao.wordpress.com/2015/11/19/275a-notes-5-variants-of-the-central-limit-theorem/ , a number of LaTeX fragments are rendering correctly but most are not. My best guess here is that this is due to caching – the ones which render are relatively small (though there are some longer ones), but they seem to have all appeared in previous posts of mine (that predate the issue).
-
Additionally I have reproduced this behavior on wordpress.com, using a free blog site:
https://malcolmginblog.wordpress.com/2015/11/20/testing-latex/My body HTML:
$latex (82,000)_{10}$My view of the error. (hi res full screenshot, browser at 100% zoom, latex with parentheses).
Note that the rendering host is still http://s0.wp.com/latex.php for me.

If you look at your source for your generated page, you can see the place where the latex goes in the text. It’s a long image tag, like mine:
<img src=’https://s0.wp.com/latex.php?latex=%2882%2C000%29_%7B10%7D&bg=ffffff&fg=000000&s=0′ alt='(82,000)_{10}’ title='(82,000)_{10}’ class=’latex’ />In that image tag, you can see the string, “https://s0.wp.com/latex.php”. This is the PHP script that WordPress hosts that’s generating the LaTeX markup as an image in inserting it in place of the LaTeX markup code, $latex (82,000)_{10}$
-
Thanks. I see the same WordPress host as you,
‘https://s0.wp.com/latex.php’So how do we get WordPress’ attention? I’m new to getting support, since this is the first real problem I’ve had.
-
Well, I keep adding the “modlook” tag to this thread.
Also I’ve got some contact from Jetpack. I let them off the hook in terms of support since not everyone getting this error is using Jetpack, but I have asked them if they know anyone on the WordPress.com staff who might be able to help.

Hi everyone!
I’ve gone through all of your comments and opened the links you’ve provided, however I am unable to help with issues on self hosted WordPress.org sites. I am only able to help with issues related specifically to WordPress.com.
I haven’t seen any rendering errors on the sites I’ve visited from this thread. Can one of you please take a screenshot of how the post looks to you and upload it to your Media Library. Drop a link to the file from your Library back in this thread when you’ve done that.
@chadmspooner – Can you please link me to a specific post on your site that you’re having trouble with? You mentioned that you see these errors when you preview a post after writing it. Does the code work once the post is published?
@teorth – I’m not seeing any rendering errors on the post you linked to:
Can you please let me know the browser and version you’re using, your operating system, and a link to a screenshot uploaded to your Media Library?
@malcolmgin – Since your site is not on WordPress.com, I won’t be able to help you debug this. If you are able to find the source of this issue, please open a new ticket in WordPress.org’s Trac:
