The same bug is reported in forum "Assistance technique" of course "Moodle en Français" :
http://moodle.org/mod/forum/discuss.php?d=90329#p554760

I get this bug when I try to restore in Moodle 1.8.5+ a course backed up in Moodle 1.8.2.
The restore stops after having displayed :
---------------------------------
  • Création d'un nouveau cours
    • Projet de système d'information 2008 et 2009 (PSI-GIS4-08)
    • Catégorie: Divers
    • N'utilise pas de numéro idnumber pour éviter les collisions
  • Creating the Restorelog.html in the course backup folder
  • Création des sections
  • Création des utilisateurs
    . . . . . . . . . . . . . . . . . . . . . . . . . . . (Nouveau: 91, Existant: 1)
  • Création des catégories et des questions
  • Copie des fichiers utilisateurs. . . . . . . . . . . . . . . . . . . .

    • Fichiers/dossiers: 2
  • Création des barèmes
  • Création des groupes . . . . . . . . .
  • Création des groupements
  • Création du calendrier
  • Création des modules de cours
-----------------------------------------

When I enter in the restored course, I get the attached view : the course contains no lateral blocks, all the sections exist. All the icons of all activities and ressources exist, but without title.
And when I try to open or edit a ressource or an activity, I get errors :
"The required instance of this module doesn't exist"
"Course Module ID was incorrect"

Thanks for any help.

This is happening here as well. All the files seem to be in the right place in the course files area, but nothing actually works. This is a backup and restore from the same version of moodle (1.9.2+). Any tips?

Hi all,

I'm currently having the same problem trying to migrate course content from a 1.8.6 to a 1.9.7

What I can tell you is that the course I am working with contains a SCORM package and if I don't include the SCORM package in the backup then the restore proceeds OK. The problem then is that none of the grades are recorded... which is what my client wants sad

I've created a new issue in the tracker here: http://tracker.moodle.org/browse/MDL-21136

Hope this helps,

Ian

Hi got same type of problem. However Moodle 1.9.5. Restoring to and from this version.

After setting Debug Messages to "Normal" (Site administration > Server > Debugging ) I get the error

Creating course modules
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 16 bytes) in D:\moodle2\htdocs\demo\lib\xmlize.php on line 53

So this seem to lead to an out of memory problem.  As this is a memory problem I search on "memory" in the settings of Moodle. I arrived at (Site Administration > Server > Performance where you can set "Extra PHP memory limit" I set this to 256MB instead of 128MB and now my restore ran OK.

Hi, I am having the same problems, and doing the steps above to increase the php memory limit did not help.  My error  keeps saying ' Could Not Restore Modules' and that is it.  Help please anyone, I can't get my course up!!

I get exactly the same problem.  Am trying to move a course from on instance of MOODLE 1.9 to another MOODLE (also 1.9).  I reset the memory, but this doesn't solve the problem.  This is a real pain. sad

Ditto.

I've tried all kinds of things and can't get anything other than a very small course to back up and as long as it doesn't contain any quizzes. Not really a very practical backup or restore.

Manually backing up course files and unchecking the include course files option helps. At the moment, I have to export then import quiz questions as Moodle XML and then go through the painstaking process of recreating the quiz module instances. This also means keeping an exact mirror of courses on my testing server and using that as a point of reference.

This is a pressing issue that I'd like to see resolved too.

Did you check that the new PHP memory limit is actually larger than the size of the zip file? This might help.

Quizes are definetely the weak link in the back-up process. I would also like to see this problem solved.

Cheers!

Hi there,

This is my problem too and has been for a long while though my problem comes through Hot Potatoes/QuizPort. Just one course and 40 users but all very busy with Hot Pots and one week into the course I can no longer backup the course with user data it - it times out.  I'm on shared hosting and from what a developer (Tim Hunt, I think) said about a year ago, I just have to live with it because I can't afford a dedicated server. I make weekly backups of the gradebook and, now I use ForumNG, I export that to Word. But it's not very satisfactory - and time consuming.

I hope things will be better on Moodle 2.

Not so cheerful,

Glenys

Re: Unable to restore course - Stops at creating course modules

by Eric Broach -

We have been having the same exact problem with our Moodle system since it was installed almost two years ago, even after upgrading to the latest version of Moodle. Whenever I backup any course on our Development or Production server according to the instructions on Moodle Docs and then try to restore it to a new course, I get an "An error has occurred and the restore could not be completed!" error. It does this regardless of whether or not the course includes quizzes, .zip SCORM packages, or any course files.

In fact, I created the tiniest course possible (just 1 topic, 1 label, and a one-sentence text page), and I still got the same error. I also turned on Normal debugging as suggested, and I didn't see any kind of "fatal error" or "memory out" message. I'm attaching a screen shot of that latest example to this message.

This issue is a serious problem for our Training Department, and it causes tons of headaches and unnecessary manual work. If anyone has any advice at all, it would be greatly appreciated.

 

Thanks very much,

Hi Eric,

small courses shouldn't be a problem at all so, could you, please, create one new issue in the Moodle Tracker, attaching the offending zip course just to be able to test restore it here? That would help to detect any problem properly or to see if it is something not happening in all installations. If you have any privacy concerns with sharing that course, feel free to contact me by email or whatever.

Also, I'd recommend you to run the restore process with debug set to developer level and look to web server logs to see if any information is sent there when you execute the problematic restore.

Finally, take a look to Backup FAQ Docs page. It's good to have it always present.

All this apart from the well-known limits of restore in Moodle 1.9.x with big courses, where both unzipping and (specially) quizzes with tons of attempts can cause problems. See MDL-15489 for more info about that issue.

Ciao smile

Thanks very much for the advice. One quick question: is this known to still be an issue in Moodle 2.0? We're thinking about upgrading our Dev server and seeing if the issue is still there...

Thanks,

Eric

1. I tried to restore my Moodle 1.99 to Moodle 2.0 and it said that it could not perform this function yet, that it is coming in the future. Am I imagining this or has someone else had this experience?
2. I will try and backup again with no test files or history of any kind and see it that works.
Anybody that has any weird problems with Moodle, I really appreciate when you post. t least that way I don't feel like I'm the only one being fitted for a straight-jacket.
This forum is really great. Thank you everyone.

Eric, the backup and restore process has been completely rewritten for Moodle 2.0, so it's very unlikely you'll have the same issue.

Javon, please note that it is not currently possible to backup a course on a 1.9 site and restore it to a 2.0 site, however the functionality will be available in a forthcoming 2.0.x release (after the release of 2.0) (source: Backup and restore FAQ).

Hello.

With "memory_limit and all", may I presume that you also increased "max_execution_time"?

This bug comments have very insightful information about backup/restore problems, as Stronk7 pointed out. Check it.

Try to turn debug on and check and post the errors that are reported.

Specify OS, web server and database in use  (type and versions), and Moodle and PHP versions.

Greetings.

We are getting a similar error in 2.0  We have tried 2.0.1 and 2.0.2 and verified in both running with Postgres.  When backing up and restoring an existing course, getting a incorrect pool file content da39a3ee5e6b4b0d3255bfef956 error and not working.  We also had the same problem trying to restore from a b/u on a 2.0.2 trial server onto a production 2.0.2 server.  Anyone else?

A follow up.  We've tried changing our Posgres db to mysql, and still get the same error.  We try backing up a course in 2.0.2 and then restore and still get the same error - incorrect pool file content da39a3ee5e6b4b0d3255bfef95601890afd80709

Interestingly we can take a systems b/u dated April 13th on our 2.0.2 test server and it restores ok on our production server, and yet one on the 15th gives us the error.  Nothing has changed on our test server, no updates, etc.  Sometimes part of the course gets restored but never complete.  A mystery...

We found the problem was related to the Respondus plugin/add on.  By removing the addon the problem went away and we tested this several times.  The Respondus plugin was added on April 14th so I'm not sure if it's been updated since then.  Hopefully this will save others some grief!
