We recently changed hosts, updated our moodle from 4.1.8 to 4.4. We've updated everything we can and worked out most of the bugs, but are unable to figure out this one.
For a handful of our courses, we are receiving the following error:
error/The instance is not properly configured, invalid path.
1. We duplicated a course to try and see if a new course would work, but when we try and change the title and save, get the above error.
2. When we log in as a teacher/student, and try and view courses, we get the exact same error.
3. For some courses, if we try and view a course, we get the same error.
I am thinking that something was missed in the migration? But if someone could direct me as to what to check, I can poke around.
The host sent us this debug, but we cannot figure out why or what is causing this issue. They seem to think that it is related to the plugin File System, but we are not sure anyone is using that functionality. Any ideas how we can track down what this could be?
