Hi @regis
Thanks for reaching out!
I was (i said i was because i rolled back to Ironwood) having this issue with Tutor 10.1.0 and Minio 10.1.0. (No S3 was in use)
Yes, the srt file name had a special character … But that was not a problem in Ironwood!
What was strange, Juniper failed to import the srt file of the default video (that of the founder of openedx). Juniper generates the 500 error too…it has no special character tough!
Sorry i cannot reproduce the error (as I downgraded Tutor)… but @juansele seems to have a similar issue, he may provide the log file…
Moreover, the decision to remove the vertical navigation in course main page is “questionable”. Very disappoinintg is the least to say. See Sections and Subsections' strange behavior on Fresh Install
At least, there could have been an option admins can decide if they want to enable or disable this feature…
Thanks
