Total guess ... but ...
Original error:
Adhoc task custom data: {"backupid":"9e3be2a63e83b2346f4a6e7bc917e01a"}
.
Is 9e3be2a63e83b2346f4a6e7bc917e01a a directory in moodledata/temp/backup/? If so does it contain - a users.xml?
Then later in error:
Call to a member function allow_unenrol()
Huh? So was the .mbz file a no user or did it include users?
Difference in enrollment methods of the sites?
Run query of mdl_courses where course title is one seen in the progress report.
Any of those have something like pending?
Really strange and dunno! :|
