Hi all,
Some context, I have just upgraded Moodle from 4.2 to 4.4 recently. Stumble upon this issue when using course reuse/restore to restore the backup into a new course. Backup is working as expected, however trying to restore the course throw some errors where the course is pending for restore.
I put on my developer hat and trying to identify the problem. When choosing the restore options, I can see the course entry created in mdl_course table in the db.
For example
ID: 2903
Fullname: Course restoration in progress copy 1
All is well, until when i click "perform restore". The entry is delete from the mdl_course table. And then I get this error:
dml_missing_record_exception
Can't find data record in database table course. (SELECT id,category FROM {course} WHERE id = ? [array ( 0 => 8432, )])
The ID 8432 seems out of place, as the created new course ID should have been 2903, as per the example above. Upon checking further 8432 seems to be the latest id for an entry in mdl_customfield_data. I am using 4 custom fields in my courses for various meta details. For some reason the backup tool is refering to the wrong ID, so I am wondering if anyone has a fix?
