Hello, i try to upgrade moodle 1.9.3+ to 2.2.11 and the process is fail. First there were issues with some Extend modules that I removed but now the upgrade process show error:
System
Error writing to database
Debug info: Table 'moodle.mdl_question' doesn't exist
UPDATE mdl_question SET parent = id WHERE qtype = 'random' AND parent <> id
[array (
)]
UPDATE mdl_question SET parent = id WHERE qtype = 'random' AND parent <> id
[array (
)]
Stack trace:
- line 397 of \lib\dml\moodle_database.php: dml_write_exception thrown

Any suggestion on this? I'm not very good at PHP and MySQL.
Thank you in advance!
