Dear forum
am using Moodle 2.2+ (Build: 20111209).
When I click on any lesson link I get this error: Notice: Undefined index: 20 in /home/learneng/public_html/moodle/mod/lesson/locallib.php on line 2685
Fatal error: Call to undefined method lesson_page_type_manager::callback_on_view() in/home/learneng/public_html/moodle/mod/lesson/view.php
no lessons display. Can anyone help mot recover the lessons ? Any help would be much appreciated.
Sorry, not seen such before, so following is 'exploration' ...
Suggest turning on debugging first and attempt to access a Lesson again (or is this the output of that below?)
Notice: Undefined index: 20 in /home/learneng/public_html/moodle/mod/lesson/locallib.php on line 2685
The function that contains line 2685 of a 2.2.x:
* This function loads ALL pages that belong to the lesson.
The specific line:
public function load_all_pages(lesson $lesson)
From the error Undefined Index … could be the mdl_lesson table is in need of repair - an index needs to be rebuilt for it.
What do you get with:
select * from `mdl_lesson`
using any DB tool to which you have access.

Hi Ken
I've run the query and everything looks fine I also checked on mdl_lesson_pages and that seems fine too.
On other thing -- I tried to run a backup and got this :
Warning: require_once(/home/learneng/public_html/moodle/backup/util/factories/backup_factory.class.php) [function.require-once]: failed to open stream: No such file or directory in /home/learneng/public_html/moodle/backup/util/includes/backup_includes.php on line 38
Fatal error: require_once() [function.require]: Failed opening required '/home/learneng/public_html/moodle/backup/util/factories/backup_factory.class.php' (include_path='/home/learneng/public_html/moodle/lib/zend:/home/learneng/public_html/moodle/lib/pear:.:/usr/lib/php:/usr/local/lib/php') in /home/learneng/public_html/moodle/backup/util/includes/backup_includes.php on line 38
not sure if it's related.
Thanks for your attention
Oliver
Just thought of something that might work ... can you create a new lesson? Doesn't need to be complete ... just something basic/simple. Sometimes, creating something new triggers other things related to the mod ... like re-indexing.

Hi Ken
Thanks so much for your advice. When I set up a new lesson and add a question page I get this on top of the page :
Notice: Use of undefined constant LESSON_PAGE_MULTICHOICE - assumed 'LESSON_PAGE_MULTICHOICE' in /home/learneng/public_html/moodle/mod/lesson/editpage_form.php on line 52
There's an empty dropdown box where the question options should be so I can't add a question page.
Thanks again
The constant LESSON_PAGE_MULTICHOICE is defined in moodle\mod\lesson\pagetypes\multichoice.php
Can you check that you have all the necessary Lesson files on your Moodle site, including that particular file, and that none of your files are corrupted?

Hi Joseph
Thanks for your insight -- pagetypes is empty . I'm going to copy over the needed files from the installation files and see what happens. This might explain the issue I've been having.
Thanks
Oliver
Dear Joseph
Success !
All lessons are restored. Thanks so much -- really appreciated.
I also copied over util files and that's fixed the backup issue.
I've learned a lot.
Thanks
Let's back track here a little ... operating system is linux, but which distro? Assuming remotely hosted ... what provider? Other info: PHP version. *How was it installed?* manually or some button installer from hosting provider?
+1 to what Joseph asked!!!

Dear Ken
All Ok now. Thanks for your attention and help.
Regards
oliver
Glad it's resolved ... Suggest you rate Joseph's post as 'useful'.
And have yet another suggestion for you ... if those files were missing, what other files might be missing? If one runs into other issues, that would be the first thing to check - are the files there? For pondering ... why weren't the files there? Were they there before?
