The [seo.enable_anonymous_courseware_access] Waffle flag seems to work in Tutor 13.1.11 but not in 13.2.2 (or 2.0 and 2.1 for that matter). The only difference I can find is that 13.1.11 has MFE plugin 13.0.2 while 13.2.2. uses MFE plugin version 13.0.4. Is this relevant? Any ideas about what can cause this problem?
Thanks in advance,
Helge Hoivik
It worked for me after I cleared the cache:
tutor local run lms ./manage.py lms shell -c "from django.core.cache import cache; cache.clear()"
Thanks for feedback and suggestion. I did a clean install and flushed the cache.
Same result …
Any further hints?
Thanks in advance!

This is the environment for the recent test installations. I run Ubuntu update & upgrade before installation and follow the instructions at Releases · overhangio/tutor · GitHub
@helgeh I moved your last post here to keep the conversation focused.

It seems to me that there is a problem with CORS (Cross Origin Resource Sharing) so that requests for apps.xxx is blocked by the browser since it is not delivered over HTTPS.
I am using the URL: kladde.online
Browsers have problems with apps.kladde.online, while prefix for studio and review works fine.
Problem with Course | KLADDE.ONLINE
but not with
https://studio.kladde.online/course/course-v1:MOOCAHUSET+2022-901+1
Browser Console shows:
11Mixed Content: The page at ‘’ was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint ‘’. This request has been blocked; the content must be served over HTTPS.
I am using Cloudflare with Automatic HTTPS Rewrites activated
Does anyone know if this require an additional header from Tutor or if it should be handled by the client browser (or Cloudflare CDN)?
Thanks for all previous tips and feedback!

Is Cloudflare handling SSL termination? What is the output of tutor config printvalue ENABLE_HTTPS?
Was “FALSE”
When turning off “Automatic HTTPS rewrites” in Cloudflare, the error persist in standard Chrome browser, but not in Beta version 102.0.5005.61
I did therefore run “tutor local quickstart” with ENABLE_HTTPS set to YES.
Turning “Automatic rewrites HTTPS” on and off in Cloudflare.
Error on all browser with message “ERR_TOO_MANY_REDIRECTS” and Console message “(index):6772 crbug/1173575, non-JS module files deprecated.”
Trying to investigate a bit more I have set up two servers in identical ways except for ENABLE_HTTPS set to FALSE (N) and TRUE (Y) respectively.
I am not well versed on how this works, but it seems that there is a problem with CORS (Cross-Origins Resource Sharing) where Chrome in some cases does not accept images that are served over HTTP.
Is this related to the ENABLE_HTTPS-function in Tutor, i.e. that some elements are sent over HTTPS and others are sent over HTTP?
Here are outputs from the Chrome Developer Tools Console for the standard Chrome browser (latest version) and the Chrome Beta browser. The two do not behave identically.

If you want to use HTTPS, then you must keep ENABLE_HTTPS=True and configure Caddy to not act as the web proxy. Please read the docs: Running Open edX behind a web proxy — Tutor documentation
To be honest, I find it quite deplorable that you write such a rant complaining that Tutor does not work for you when you did not even bother mentioning the important fact that you are running your platform behind a proxy.
Thank you for following up on this!
“Deplorable” is strong language. I understand that this case provoked you. I was, on my side, increasingly irritated by the “public-relation” profile of simplicity that you have developed. The use of Tutor is in fact quite complex and in continuous change. Maybe you could also look into this side of the matter?
I have tested with and without the proxy with the same results so it was not that I “did not bother”.
Bygone is bygone. I appreciate the substantial work that is put into Tutor and online support. I look forward to try out Nutmeg with and without the proxy.
regards,
Helge
Update and closure of this thread:
Using Tutor v13.2.3 today with
and Cloudflare with
the site on https://revisjon.online now works with
Chrome version 102.0.5005.63 without 40x errors.
Thank you for support, Regis!
