Import in Moodle 2.0 does not work!

Import in Moodle 2.0 does not work!

Hi!

I've been installing Moodle 2.0 and found that the import functionality does not work. When I click on import and choose the course from which I shall import, then click continue.... everything seems fine, but when I check the course, I find that nothing had been imported!

Did anyone face this issue before?

Thanks in advance!

Yes...we are having this exact issue.  I've tried about everything I can think of.  I can backup and restore the course without an issue BUT we cannot use the course import.  It says it completed successfully but when you go into the course there is nothing there.  We have upgraded to the latest Moodle 2.11 thinking that would help our situation.  Our teachers are used to using the course import ... I tried the methods I found on the Moodle.Org site...permissions and increasing the number of courses to display but can't seem to get this to work.

If you put debugging into developer mode, what does it show?

Hi,

In regard to this import error, I posted here on 2 December without response: http://moodle.org/mod/forum/discuss.php?d=182312

Here's what I posted, including the debugging trace:

Hi,

I posted this issue/question elsewhere in October without any reply. Hope to have better luck with this thread.

Our teachers receive the error message "error/decode_rule_mappings_incorrect_count," bringing everything to a halt, when trying to duplicate, restore, or import. Visually, it appears the operation failed. However, as soon as the teacher creates a new resource (such as a Book) in the course, all the items miraculously appear as would have been expected in the first place.

The same behavior is seen repeatedly during testing with various courses on our production server (Moodle 2.1.2+ (Build: 20111012)) as well as our sandbox (Moodle 2.1.3 (Build: 20111128)).

All three (duplicate, restore, import) seem to fail in /backup/util/helper/restore_decode_rule.class.php.

Any ideas?

Here's the trace from a restore:

error/decode_rule_mappings_incorrect_count

We had problems with an add on causing a problem with the backup. You may wish to attempt removing any add ons then attempting a backup/restore.

Hi,

Thanks for the tip, but can you be more specific? Do you know which "add on" was causing the problem?

Yes, I found that some questions were the culprits and sometimes it was just one course that caused problems.  Most of the time, I never did figure out exactly which one as I was lucky enough where the teacher with the issue had another section that she was able to import from.  The error does not look familiar to what I was seeing prior.

The other error I had was a failure to restore to a new course but I was able to rectify that creating the course and the sections in the course before restoring.  You might check and see if the course that you are restoring into has enough sections in it.

The question module has been known to cause issues, in particular Cloze questions (of which I have hundreds of course!).  At least you have found a work around - have you submitted a tracker ticket?

In our case it was Big Blue Button. After we reinstalled it we had no problems. If you read through the forums there were other Moodle users with other add ons causing the similar problems. Best of luck!

We were having the same issue.  I deleted the Slideshow Mod and the import worked.

Yes, you are right Jonathan. 

In my case QuickMail block was the issue.

 

Thanks

Hi,

Although none of our users were actually utilizing it at all, it appears the "Presenter" module was the culprit. Once it was uninstalled, the fatal errors generated by the duplicate, restore, and import functions vanished.

I manage anbout 8 different sites and a few of them have this healthcenter fault and for the life of me I can not see why.

PLEASE can anyone help
