I can't provide diagnostic links because the server is only accessible on the internal network:
Output from the session_test.php is:

$_SESSION['test'] is set to: TRUE


When trying to upgrade from 2.0 to 2.3, I go to the install folder but the web page doesn't load. I have these errors in the server log:

Probably a corrupted settings file.

Try pasting this to the bottom of your "hesk_settings.inc.php" file:
If that doesn't work try backing up to 2.0 for now as I will not be able to reply to any further inquiries before 16th I'm afraid.

Your suggestion worked but now I get an error at stage 4 of the install:

ERROR: hesk_kb_attachments table exists
Database table hesk_kb_attachments exists on the server, your Hesk had already been updated to version 2.3!

If I ignore the error, everything seems to work but submitting a ticket fails with:
Error:
Can't execute SQL

I would like to think that I restored everything back to version 2.0, including the database but now I'm not so sure. However, an old backup of the database, taken before my attempted upgrade, does have a hesk_kb_attachments table with no records in it.

Can you let me know exactly what HESK table names are inside your database?

There is another SQL error which I didn't notice before. Anyway, here are the tables before the upgrade:

mysql> show tables;
+---------------------+
| Tables_in_heskug |
+---------------------+
| hesk_attachments |
| hesk_categories |
| hesk_kb_articles |
| hesk_kb_attachments |
| hesk_kb_categories |
| hesk_mail |
| hesk_notes |
| hesk_replies |
| hesk_std_replies |
| hesk_tickets |
| hesk_users |
+---------------------+
11 rows in set (0.00 sec

When upgrading, the first error is:

Error:
Can't execute SQL: ALTER TABLE `hesk_tickets` ADD INDEX (`owner`)
MySQL said:
Key column 'owner' doesn't exist in table

I've looked at the original database and there is indeed no field "owner". If I try again to upgrade, then I get the error:
ERROR: hesk_kb_attachments table exists

The databse has been changed by the failed upgrade. It now looks like this:

mysql> show tables;
+---------------------+
| Tables_in_heskug |
+---------------------+
| hesk_attachments |
| hesk_categories |
| hesk_kb_articles |
| hesk_kb_attachments |
| hesk_kb_categories |
| hesk_logins |
| hesk_mail |
| hesk_notes |
| hesk_online |
| hesk_replies |
| hesk_std_replies |
| hesk_tickets |
| hesk_users |
+---------------------+
13 rows in set (0.00 sec)

Because of the failed update and new tables installed the update script actually wants to upgrade from a later version now, not 2.0.

You do have MySQL backup before the upgrade? Try deleting all tables, restoring backup before first update attempt (without any new tables) then try upgrading again.

If that doesn't work and you don't have much tickets/articles it might be best to do a clean install of 2.3 to make sure it's 100% working correctly.
