Got an error after update from 2.5.3 to 2.6.1

[mustang325]

Script URL: http://www.hesk.com/
Version of script: 2.6.1
Hosting company: sweb.ru
PHP version: 5.3.29
MySQL: 5.1.73

After update from 2.5.3 to 2.6.1 I got messed up list of tickets
I fugured out if I use new file ticket_list.inc.php from 2.6.1 - I have this problem. If I restore older version of this file - 2.5.3 - then I see almost normal list, but I if I get into ticket - I can see only customer's text. None all staff's replies disappear

I also checked if update script (from install directory) finished DB convertation. It is, at least partly - I have all new fields and indexes. Perhaps second part of conversion is failed - update exisiting data

I'm not a professional in PHP and SQL, so the best way is script for phpMyAdmin that fix this situation, if not - at least direction where to look. My base is not huge - I can put it somewhere to check it out.

My small payment is Russian translation of HESK 2.6.1 is already published

If you followed update instructions in the docs and update.php file finished, then the database must have been updated fully.

Mixing files between different versions is not recommended and will, of course, not work correctly.

Make sure you are using all the 2.6.1 files then let us know that exactly is wrong. Just "I got messed up list of tickets" doesn't say much, what exactly is wrong and how do you expect it to be?
