There are NO “configuration changes” being made to the server. The site is hosted on WP Engine, one of the most respected, well-run hosting companies on earth. If any significant changes were being made on the server I am confident I would know about it.

So, today…suddenly the Preview function is working on the same document that I could not get it to work on yesterday! Shakin’ my head. What changed that would have “fixed” this???

Yes, it is very strange. Never had this issue before with any child theme. Yes, the link you provided is where I generated the child theme. Made no manual changes at all — just installed it. I will open a support ticket about this. this isn’t really getting in the way of anything we’re doing on the site — it just makes me nervous that there is some sort of incompatibility/conflict going on.

By the way, when I click the Preview option now, a gray semi-transparent background fills the screen, then a small white strip drops down at the top of the screen with nothing but a “Close” button on it.

One more comment: I think the concept is spot on. The execution is atrocious!

Thank you again for your thoughts. One question: when you say, “Changes in global preamble cause page load delay only once.” do you mean the delay occurs only once for the entire site, or once per user session, or…?

Regarding your suggestions, there is no problem with the overall performance of the site. The local cache option is enabled in QL, and there is already a caching plugin installed and active.

Okay, I see what you mean. Sometimes (not all the time) it takes about 30 seconds for the page to display initially. And sometimes (not all the time) it comes up with blank content, but when I refresh the page, the content does display. The behavior seems somewhat random. Would this kind of behavior vary depending on the particular package combination I use? I will run some more tests. Visitors to the website expect fast response time (no more than 10 seconds at the absolute maximum), and certainly won’t put up with having to refresh a page to see the content. If I can’t do that by overriding the global packages, I won’t be able to use that feature.

Thank you for your continued help and patience. I have executed several tests using the preambles displayed on the page that you referenced. They seem to work fine when you add a [preamble] shortcode to a particular math term on the example page on my site.

However, what I want to do is to have the packages replace the global packages in the Advanced tab of the plugin. This is not working — at least not how I am doing it. To run these tests, I am <removing the default packages from the global tab (\usepackage{amsmath} \usepackage{amsfonts} and \usepackage{amssymb}) and replacing those terms with the terms from your exaqmple page, e.g., \usepackage{mathptmx} and \usepackage{avant}). When I do this, the example page comes up blank, i.e., none of the content on the page displays. (And it takes about 20 seconds for the page to refresh.)

Obviously, I am doing something wrong here. Can you tell me what it is?

Just to be clear, this is what I am inserting into the tab where you enter the preamble:
\usepackage{mathptmx}

A broader question related to this: is there documentation somewhere that identifies the packages that QuickLatex has access to? Given the results I am getting, it appears that mathptmx is not one of them.

Ok, I got it. Thanks again. We can close this. Cheers!

Thank you for your reply! I was able to figure out how to set the font size and color for a particular equation by applying the example that is on the first tab of the settings. I had seen that before but did not understand exactly where to put the modifying term. In any case, it works!

Regarding your response about modifying the font itself…I read the words, but don’t understand exactly how to proceed. I understand how to install new fonts in WordPress, but how do I apply a particular font to either all equations on the page, or just to a particular equation??

Excellent! Thanks for the response. Cheers.

Sorry, am confused by your reply, @chrisjean Does this mean you are planning to address this issue?
