Sage Cells and PreTeXt

[Thomas Judson]

I am having problems with Sage cells in my ODE book. Everything worked well until about a month or two ago, when I updated Safari. Now Sage cells no longer appear in Safari when I load a local file. The solution was to change to Google Chrome. Things worked in Chrome for a while. Now Sage cells will appear in Chrome but not execute. Firefox can’t even find the CSS for PreTeXt.

If I upload the HTML version to the web, the Sage cells display properly in both Safari and Chrome (Firefox is still worthless). I always text the Sage cell code in Sage or CoCalc before putting it into the PreTeXt document; however, it would be very nice to be able to copy edit and debug before sending something out to the entire world. Ideas?

I've deployed a big rewrite of SageMathCell a few weeks ago which may or may not be related. Can you provide a concrete example of what you are working with so I can reproduce the issue and try to debug it? I don't have access to Safari, but both Chrome and Firefox should work.

Google list serve will not allow me to send an archived file.  I am using my other account to send it to you directly.

Dear Tom,

Have you tried running a local server via Python, as described here:

Got it, thank you!

On Debian Stretch it works for me in Firefox, but not in Chromium with an error in console "DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document." My guess is that security policies in browsers have changed once again. I'll try figure out a fix, but you should check Rob's suggestion meanwhile.
