Hello Ken.
I sincerely appreciate your informative way of presenting explanations and solutions of issues.
The Moodle site I work on also stopped restoring courses through all methods (course restore, course copy, and import course). The same error message was produced stating xml parsing error.
After reading this thread, I had the hosting company downgrade the libxml to 2.10.4 (they said they could not degrade to 2.10.3). The restore function began working after that. One day later, the same issue occurred. I saw in the PHP info section of our Moodle site that there is also a libxml2. should I have libxml2 downgraded as well?
Also, since this issue appears to be caused by the libxml, do you think the Moodle development team will be able to provide a solution?
