Embedded sagecells not work in Chrome on mac

[Kwankyu Lee]

Hi,

Embedded sagecells do not work in the latest Chrome browser on Mac (High Sierra). The same web page works with Safari on the same machine and with Internet Explorer on a Windows machine. I remember the same web page worked with old Chrome browsers, but from some time not any more... I inspected the issue on the Chrome browser, and the error message is:

Request header field X-XSRFToken is not allowed by Access-Control-Allow-Headers in preflight response.

Is this a known issue? Is there a fix for this? The sagecells are embedded in a webpage of a Django website. I wonder if this fact is related with the issue...

Thank you in advance.

A sage cell I tried in Chrome on my Mac seemed to work fine,
so can you provide a link to one that is not working for you?

Do sage cells on other sites work for you?

I set up a test site:

http://code.chosun.ac.kr/~kwankyu/homepage/sagecell_test

which fails too. So the issue is not related with Django. Does this site work for you?

Yes. The sagecell site of SageMath homepage works fine.

It works for me in Chrome 63.0.3239.132 , which is the latest
version, on my MacBook Pro running 10.11.6 (which is not the latest OS).

Not sure how else I can help.

That is strange. First I suspected my server is misconfigured. But as it works for you, it now seems that the problem lies with my Chrome browser somehow...

That was a big help :-)  Thank  you! Now I will try to reinstall Chrome.

Shot in the dark: do you have some extensions running within Chrome?

Yes, several of them. Just now I removed all of them, but still no luck. 

According to my experiments, the latest Chrome on macOS High Sierra (on Mac Pro) seems problematic, unless someone report counter evidence.  There is no issue with the latest Chrome on El Capitan.
