I have posted about this on one other forum thread that I found this issue but there is no potential debugging info given. So I thought I'd post it again here.
I am having an issue on restoring courses (backed up from v3.1) but what is odd is that I was able to restore the first two courses to a new installation of Moodle version 3.2.1+ (Build: 20170216). But when I started trying to restore the rest of the 5 courses, I ran into this issue of error processing archive file. Debugging has been turned on and attached is a screenshot of the debug info.
New Moodle Environment: PHP 5.6.29 | MySQL 18.104.22.168.1
Can't figure this one out. Don't think file size is an issue nor are the time limits or upload limits. I have also tried uploading the .mbz files via a repository and restoring them but no luck.
Pls advice if you think I could look some place to debug this. Stumped here as I was able to restore 2 courses without any trouble. Appreciate any advice.
