Hallo All,

Here I am again. I haven't slept for a few days now. The problem is that I have a Moodle site 1.8 and the upgrading to 1.9.6+ is not working great.

I get the following errors:

(see attachment)

Here is what I did:

I'm using this script for the first problem

[code]

<?php
require_once('config.php');
require_once($CFG->dirroot . '/question/type/multianswer/db/upgrade.php');

require_login();
require_capability('moodle/site:config', get_context_instance(CONTEXT_SYSTEM));

print_header();

$db->debug = true;
question_multianswer_fix_subquestion_parents_and_categories();

print_footer('empty');
?>

[/code]

I don't know what to do with the second problem??

I've used this script for the third problem:

[code]

DELETE FROM mdl_question_categories
WHERE
 NOT EXISTS (SELECT * FROM mdl_question q WHERE q.category = mdl_question_categories.id)
AND NOT EXISTS (SELECT * FROM mdl_context con WHERE contextid = con.id)

[/code]

nothing is working and I don't know what to do????

Need help anything would be helpful

Thanks

Leon
